Hello everyone, dear readers and smartphone users. Today I will tell you what to do if, when connecting your smartphone to a personal computer, the error “USB device MTP failure” occurs. Below you can see a screenshot of this error. If you have the same problem, then read on.

The error “USB device MTP failure” can occur for several reasons, here are some of them:

1. MTP driver problem. This happens sometimes, but not on all computers. This problem can be resolved very simply and quickly; below I will describe it in more detail;
2. Incorrect settings in the device itself. As practice shows, this reason occurs in 1% of cases, but nevertheless, it is possible that this is the cause of the error for you;
3. Outdated drivers. This problem also occurs, but, just like the previous ones, this cause of the error is eliminated simple update drivers for your operating system.

So, we have sorted out the reasons, now let's start fixing this problem. Let's start in order, with the most working and common method of eliminating an unpleasant error.

Method 1

Now reconnect your mobile device to a personal computer and check whether the error that occurred earlier has disappeared.

Method 2

If the previous method did not help, then let's try to dig into the settings of the mobile device itself. Follow these steps:

Important: if the development item is not visible, then do the following: go to the “About device” section and click on the build number about 10 times. Thus, you activate the “Development” item.

Method 3

If everything is in order, but the driver for MTP Device still does not function, you can try installing it in manual mode. To do this, you need to go to “Device Manager”. If the device is not working properly or the driver is not installed, the device itself will be marked with a yellow icon. Everything is quite simple here. Find the driver update button in the properties and select only compatible devices from the list. If this operation does not help, you will have to remove the driver and then reinstall it in automatic mode.

If this does not work, tell the system the location where the installation distribution with necessary information. In some cases, this turns out to be ineffective. There could be a lot of reasons for this. In certain cases, installing a fresh version of Windows Media Player on the system can help. Most likely, you just need to check the system partition of your hard drive for errors. The problem could be anything. Sometimes it happens that the “native” media player itself issues this type errors and failures.

This option also cannot be excluded. In this situation, if you are using a version of Windows 7 or higher, you can try to disable multimedia components using the “Programs” section in the “Control Panel”. There are many reasons for such failures. Therefore, we will have to move from the simplest methods of solving this problem to more complex and radical methods. In each specific case, it is necessary to take into account the specifics of a particular device. However, as practice shows, a universal solution to this problem can be the use of the system registry.

It is quite simple in the main section HKEY_LOCAL_MACHINE by sequentially moving through the tree to find the UpperFilters key and delete it. This will not affect the performance of the operating system in any way. However, the connection will finally work as expected. It is worth immediately noting that this method in most cases, it is also effective for gadgets manufactured by Samsung.

Conclusion

In this review, we tried to briefly describe the main issues related to using a connection using MTP technology. As you can see for yourself, the user will not have to put much effort into installing the driver, unless of course you are using Linux systems. All major errors when installing drivers are quite easy to fix. However, in each case, it is still advisable to establish what the cause of the problem is. It is better to do this before performing drastic actions such as deleting system registry keys.

However, in most cases, failures should not occur, especially if you install the most latest versions additional software. In any case, you just need to turn to the official resources of mobile device manufacturers. Surely, you can find a help section on the official website, which will describe the process of dealing with problems of this type. Most likely, the problem is not even in Windows, but in disabled settings and functions or even in the device firmware.

Recently, synchronization of mobile gadgets based on Android OS with standard computer systems has undergone quite significant changes. The new technology was based on the use of the so-called MTP Device driver when directly connecting the device to a computer or laptop via a universal USB port.

What is MTP Device?

In general, MTP (Media) technology first saw the light back in 2008 on mobile gadgets with Honeycomb in the Android OS Ice Cream Sandwich. At that time it was considered integral part Windows package Media, but was then standardized as one of the main types of USB devices.

That is why now stationary operating systems, when connecting a mobile gadget, identify it as an MTP Device. In fact, the development itself was not something new, since it very much resembles the PTP (Picture Transfer Protocol) protocols, or rather, it is one of its varieties in the form of additional extensions.

MTP Device Driver as an alternative to USB Mass Storage

As for the functioning of such a system, it is probably clear that without installing a driver it is in principle impossible. However, compared to normal data exchange via USB MTP Device, the driver works slightly differently.

The most important difference, also known as the advantage of the new technology, is the following. The fact is that when using a standard connection when USB help Mass Storage creates two partitions (for media files and for applications separately), and one of them always depends on the other. A situation arises when a smartphone or tablet does not have access to one of the sections, but the computer perceives both. This is why a situation arises when applications installed on an SD card not only do not work, but do not even start.

There are no such restrictions when using MTP Device. In addition, there is no need to even use file system FAT. And if previously the redistribution of free space occurred due to the influence of one partition on another, in this case there is nothing like that. Simply put, in the past, taking up the free space of one partition resulted in reducing the size of another. Now both sections remain unchanged.

Standard driver installation on Windows

Now let's see how it's made standard installation drivers when synchronizing the device with Windows. Let's say we have a Samsung smartphone or tablet.

As a rule, usually when you first connect a device to a computer terminal, the system displays a message in the system tray that a new device has been found (in our case, MTP Device Samsung). The system itself installs the driver necessary for synchronization without any problems, after which data transfer can be carried out in the same way as using a regular USB connection, when it is determined and internal storage, and an external SD card. Of course, errors may appear (such as “Samsung Mobile MTP Device driver is not installed”), but we will dwell on them a little later.

General recommendations for installing drivers for most Android devices

In principle, it almost always works automatic installation the necessary drivers for the Windows operating system itself. However, you can also use alternative methods related to the installation of related utilities for a smartphone or tablet.

So, for example, the same Samsung MTP Device driver is installed automatically if the latest version is available Kies apps. Please note, for each specific model Samsung Corporation does not release drivers for a mobile gadget, so look for them, say, for S6 or for Galaxy Note 2 makes absolutely no sense.

For HTC smartphones, you need to use specialized software called HTC Sync Manager (sometimes you may need to install the firmware via FastBoot mode). For LG, you can find a driver on the manufacturer's official website specifically for a specific model. For Nexus, you need to use the ADB RUN utility and install the driver from the standard Device Manager. When using Sony gadgets, there are two options: installing Sony PC Suite or using FlashTool drivers. In principle, there is no difference, but you need to remember that these are two mutually exclusive programs - when installing one, you must first remove the other.

Use on Mac OS

The use of devices classified as MTP Device when synchronizing with desktop Macs or Apple laptops is not much different from its counterpart in Windows.

Unless, to be completely sure, you can additionally install Android app File Transfer, that's all. Otherwise there shouldn't be any problems.

Installation on Linux (Ubuntu)

IN Linux systems due to their specificity, installing MTP Device drivers looks somewhat more complicated. As an example, consider this process when installing a driver for Nexus.

So, we use the command window, in which we first write sudo nano -w /etc/udev/rules.d/51-android.rules (installing UDEV rules). Then enter the command SUBSYSTEM=="usb", ATTR(idVendor)=="04e8", ATTR(idProduct)=="6860", MODE="0600", OWNER="", after which we sequentially execute the lines sudo apt-get install mtpfs, sudo mkdir/media/GNexus and sudo chmod 775/media/GNexus.

Next, connect the gadget to the computer and enter sudo mtpfs -o allow_other /media/GNexus. That's it, now, using Nutilus, you can start moving any files and folders. Yes, the most important thing. When all operations are completed, remember to use the final command sudo umount mtpfs.

Possible errors and methods for eliminating them

Unfortunately, errors cannot be ruled out either. In most cases, this applies only to operating rooms Windows systems. Let's try to look at the most common failures and the simplest methods for eliminating them.

First of all, it is worth checking whether the accompanying utilities are up to date with the latest versions. When using them, it is advisable to download the latest distribution from the manufacturer’s website.

If the driver for MTP Device still does not work, you can try to reinstall it manually. To do this you need to go to “Device Manager”. In theory, if the driver is not installed or the device itself is not working properly, it will be marked with a yellow icon. Everything is simple here. You need to find the driver update button in the properties, and then select only compatible devices from the list. If this does not help, you will have to remove it and then install it again automatically. If this does not work, you will have to tell the system the location where the installation distribution containing the necessary information is stored.

Sometimes, however, this does not help. There can be any number of reasons. In some cases, installing the latest version on the system may help. Windows Media Player. You'll probably just have to check the system partition hard drive for errors, you never know what might happen. It also happens that this type of error or failure can be generated by the “native” media player itself (this option, unfortunately, cannot be ruled out). In this situation, if used Windows versions in the form of “seven” and higher, you can simply try to disable multimedia components in the programs section of the “Control Panel”.

As is already clear, the reasons for such failures are simply innumerable. Therefore, we will have to move from the simplest methods of solving the problem to more complex or even drastic ones, taking into account the specifics of the cause in each specific case and for each specific device.

However, as practice shows, one of the universal solutions can be the use of the system registry. Here you need to find the UpperFilters key in the main section HKEY_LOCAL_MACHINE by sequentially moving through the tree (System\CurrentControlSet\Control\Class) and delete it. This will not affect the performance of the operating system, but the connection will work as expected. Let us immediately note that in most cases this method can be used for gadgets from Samsung.

Conclusion

That’s basically all that concerns the main issues related to using a connection using MTP technology. As you can see, you don’t have to work hard to install the driver, except on Linux. Basic errors can be resolved quite easily, but in each case it is advisable to find out the root cause before taking any drastic actions like deleting registry keys. But in most cases there should be no failures, especially if you install the latest versions of additional software for your gadget.

In any case, you can simply turn to the official Internet resources of mobile equipment manufacturers. Surely there is a help section with a description of problems of this type. Perhaps the problem is not even in Windows, but, for example, in the device’s firmware or disabled functions and settings.

Android from A to Z: What lies behind the abbreviation MTP, and how to use it correctly

MTP (Media Transfer Protocol) first appeared on devices with Honeycomb. The protocol is slightly different from the usual USB Mass Storage (UMS), in which you turn on the USB mod and start moving files. And since MTP became part of it, it would be nice to find out all the nuances. In this post we will try to understand as much as possible what exactly this protocol is, what is the need for it, and how to configure it to simplify file transfer.

What is MTP?

MTP is a set of custom extensions for PTP (Picture Transfer Protocol), which is aimed at transferring files and associated metadata across USB. Still here? Then let's continue.

Originally part of the structure Windows Media, but in 2008 MTP was standardized as a type USB devices, thereby becoming an established standard. If you have owned an iriver or Creative MP3 player, you have probably encountered MTP. If you use a digital camera, which is automatically recognized as a device when connected to a PC, then the RTR, which is essentially the same as MTP. The thing is quite old, but not for Android.

Why use MTP instead of USB Mass Storage?

The essence of use MTP is that now manufacturers of mobile devices do not need to create two separate sections, one for applications, the second for media files. Previously, a sin was noticed behind them, which consisted in expanding the second partition at the expense of the first, and this very often led to a lack of space for new applications. WITH MTP Both types of files can be stored together.

U USB Mass Storage There is one big drawback - when you create memory partitions, one of them is completely at the mercy of the other device. This means that your tablet or smartphone will not have access to this section, but the computer to which the device is connected can manage it in every possible way. For this reason, some applications and, especially, widgets placed on the SD card do not work.

Another advantage MTP is no need to use file FAT systems for storage. This ultimately leads to faster operation of the device.

Installation of MTP

From the time of Windows XPMTPdevices work without problems. Connect yourGalaxyNexus, choose MTPAs a connection type, the computer operating system itself finds the necessary drivers, you will only need to wait a little. Moving files between your smartphone and PC without any problems is ensured. But what should those users who preferredLinux And Mac?

MacOS

Install UDEV rule opening rules file via terminal

sudo nano -w /etc/udev/rules.d/51-android.rules

Then enter next line at the bottom of the file (remember to include your username):

SUBSYSTEM=="usb", ATTR(idVendor)=="04e8", ATTR(idProduct)=="6860", MODE="0600", OWNER=" "

After which it will be the turn for:

• sudo apt-get install mtpfs
• sudo mkdir /media/GNexus
• sudo chmod 775 /media/GNexus

Then you should connect Galaxy Nexus to the PC and in the same window as before enter:

sudo mtpfs -o allow_other /media/GNexus

This will all allow you to drag and drop files using Nautilus, and don't forget to enter the following command when finished:

sudo umount mtpfs

Alternative

Alternatively you can use the combination Wifi File Explorer And QuickSSHd And send files over a wireless connection.

Troubleshooting

1/ The device is not detected at all

• These drivers are for Intel® devices only. If you are using a device made by one of the OEMs, please obtain drivers directly from the manufacturer's website or use the links provided by Google.

2/ I have errors in the Manager Windows devices

• Open Windows Device Manager:
  • You can detect the element USB Mass Storage instead of ADB Device. In this case, click the Mass Storage device icon right click mouse and select ‘Delete’.
    
  • You can see Android device icon with yellow exclamation point . In this case, right-click the Android device icon and select ‘Uninstall’.
    Then disconnect the device from the computer and run the driver installer again.

3/ Portable device shows up but there is no Android Debug Bridge (ADB) profile

You may not have enabled the USB Debugging option.
By default, developer options are hidden on your phone. Open the settings menu on your phone and find the section About the phone. Scroll down and find the "Assembly" item. Click it five times and you should see a small dialog telling you that you have enabled developer features.
Return to the main settings menu and open Developer Options and then turn on BeDebugging.

4/ I'm still using Windows XP. After activating MTP, the pop-up dialog that should allow access to the phone's file system or transferring media files does not appear.

By default, MTP is not supported on Windows XP. You must install Windows application Media Player 10 or newer version.

Additional questions and support
For other troubleshooting support, post your questions on the forum Intel support for Android developers on the page: ()

If you are reading this article, then it is obvious that you are having problems transferring files via USB on your Android device. Don't worry, you are not the first person to contact us with such a question.

Fortunately, we know several ways to solve this problem. So, without further ado, here's what you need to do to get USB file transfer working again.

Cause of USB file transfer error

There are several reasons why you may not be able to transfer files via USB:

• USB cable does not support file transfer
• The device is not configured to accept files via USB
• You have installed Samsung app Kies
• The Micro-USB port on your Android device is broken (unfortunately I can't help you with that)

Step 1 - Enable file transfer on your Android device

This is the first thing you should do to be able to transfer files via USB to your Android device.

To enable USB file transfer, go to Settings>Storage>Tap on the three vertical dots in the top right corner of the screen> USB connections to your computer > Check the box next to "Media device (MTP)"

If you think the problem with USB file transfer is software related, try connecting the device to your computer using USB, select "Camera (PTP)" and put it away again. This helps some users.

Step 1.1 - addition for the “clean” version of Android 6.0 Marshmallow

If you don't see the above option under Memory, make sure you enable USB debugging. After that, do a little trick:

1. Disconnect the USB cable from the device.
2. Enable developer mode. To do this, go to Settings > About phone > tap on the build number several times until a pop-up message appears that you have become a developer.
3. Go to Settings > Developer Options.
4. Enable USB debugging.
5. Lock your device (lock button on the side or top).
6. Connect your smartphone to your computer using a USB cable.
7. Unlock your Android device.
8. Swipe down to open the notification panel and tap on USB Charging.
9. Select "File Transfer" from the pop-up window.
10. Lock your device and unlock again.

Using this method, you will be able to transfer files via USB. For some reason this option is not available without Developer Mode enabled.

Step 2 – Uninstall Samsung Kies program

Skip this step if you do not have Samsung Kies software installed.

Samsung's official file transfer program often causes interference when transferring files via USB. To remove Samsung Kies, you need to first download the program and then select “Uninstall”.

Step 3 – Check USB Cable

Not all USB cables are created equal: some are capable of transferring files, some are not. It is recommended to use the USB cable that came with your Android device. Typically, they have a USB file transfer feature.

If none of the methods helped solve the problem, then try installing AirDroid. Given software allows you to transfer files to Android devices without a USB cable.

You can often encounter situations when a user connects a mobile device to a computer via USB cable, but the system does not recognize the device and even displays an error message. And this, unfortunately, applies not only to the most simple phones, but also to modern tablets, smartphones and even cameras or cameras. How to identify an MTP USB device, make it visible and fully operational, is then proposed to be considered in as much detail as possible. Let's try to apply several classic methods and solutions that are offered by users on the Internet.

Windows 7 error: “USB device MTP. Refusal". General essence of the problem

I would like to note right away that the problem is that the mobile device is not detected operating system solely as a drive (neither the internal partition nor the removable card is visible).

Many users think that the main reason is that the driver is not working properly. Yes, indeed, such a situation can be observed, but only partially. Sometimes the problem may be in the settings of the device itself or even in the system settings Windows registry. In addition, if some additional components and updates are not installed on the system to ensure the correct operation of connected devices of this type, the error may also appear.

Initial actions with the registry

So, before downloading the MTP USB device driver, you can take preventive measures, so to speak, using system registry, since some installed keys may contain prohibitions on identifying mobile devices.

First of all, call the editor (regedit in the “Run” menu) and go to the HKLM branch. Through the SOFTWARE section and control directories, we move to the final directory, as shown in the image above. On the right there is the UpperFilters key, which is exactly what is stopping us. We delete the entry, exit the editor and reboot the system. After this, as a rule, when you connect the device to a computer or laptop, the drivers, if they were not present, will be installed automatically, and the MTP USB device itself becomes visible in the system.

Installing or updating the driver

But it also happens that the above key is initially absent from the registry, and devices are not detected under any pretext. What to do in such a situation?

Here you need to, with the device connected to the computer, go to the “Device Manager”, find your device marked with a yellow triangle, and through the RMB menu select the driver update (you can also use the properties section). When the system starts making recommendations, you should select only compatible drivers. If this does not help, download the universal MTPPK driver from the Internet, install it yourself, or point the system to the full path to the saved file.

Sometimes a non-working MTP USB device can be identified if you select the hardware ID in the information drop-down list on the details tab, and then search for a driver on the Internet using the most long line, containing the identifiers DEV and VEN. It goes without saying that after downloading, you will also have to install the driver yourself.

Installation of additional system components

Sometimes, even if there is a working driver, the error may occur again and again. It is believed that this situation is largely due to the lack of special components of the operating system itself.

The fix for the error is to download the Windows Media Feature Pack or its missing elements from the official Microsoft website and then install it. User reviews indicate that sometimes this works.

Other troubleshooting options

Some owners of mobile equipment, after deleting the registry key described above, recommend disabling the mode. Sometimes setting the settings using the connection type PTP (camera) instead of MTP helps.

Owners of smartphones and Samsung tablets claim that to detect an MTP USB device, it is enough to install the appropriate adapter (it is installed along with the Samsung Kies program).

Another option is said to be to boot Windows into safe mode and log in as an administrator. In this case, the drivers are installed automatically and without problems.

To identify Apple mobile technology, many users recommend using the following steps. Using RMB on the system partition (drive “C”), select the properties section and the security tab, and in the groups or users menu, check for the presence of the “Authenticated” line with the “Read” parameter.

Similar actions are performed for the Windows directory. If the specified parameter is not enabled, it must be added through the change options button. After reboot Windows Apple devices will be recognized by the system.

Finally, if your system has been exposed to viruses, you should perform a full scan using portable antivirus utilities.

Android from A to Z: What lies behind the abbreviation MTP, and how to use it correctly

MTP (Media Transfer Protocol) first appeared on devices with Honeycomb. The protocol is slightly different from the usual USB Mass Storage (UMS), in which you turn on the USB mod and start moving files. And since MTP became part of it, it would be nice to find out all the nuances. In this post we will try to understand as much as possible what exactly this protocol is, what is the need for it, and how to configure it to simplify file transfer.

What is MTP?

MTP is a set of custom extensions for PTP (Picture Transfer Protocol), which is aimed at transferring files and associated metadata across USB. Still here? Then let's continue.

Originally part of the structure Windows Media, but in 2008 MTP was standardized as a type USB devices, thereby becoming an established standard. If you have owned an iriver or Creative MP3 player, you have probably encountered MTP. If you use a digital camera, which is automatically recognized as a device when connected to a PC, then the RTR, which is essentially the same as MTP. The thing is quite old, but not for Android.

Why use MTP instead of USB Mass Storage?

The essence of use MTP is that now manufacturers of mobile devices do not need to create two separate sections, one for applications, the second for media files. Previously, a sin was noticed behind them, which consisted in expanding the second partition at the expense of the first, and this very often led to a lack of space for new applications. WITH MTP Both types of files can be stored together.

U USB Mass Storage There is one big drawback - when you create memory partitions, one of them is completely at the mercy of the other device. This means that your tablet or smartphone will not have access to this section, but the computer to which the device is connected can manage it in every possible way. For this reason, some applications and, especially, widgets placed on the SD card do not work.

Another advantage MTP is no need to use the FAT file system for storage. This ultimately leads to faster operation of the device.

Installation of MTP

From the time of Windows XPMTPdevices work without problems. Connect yourGalaxyNexus, choose MTPAs a connection type, the computer operating system itself finds the necessary drivers, you will only need to wait a little. Moving files between your smartphone and PC without any problems is ensured. But what should those users who preferredLinux And Mac?

MacOS

Install UDEV rule opening rules file via terminal

sudo nano -w /etc/udev/rules.d/51-android.rules

Then enter the following line at the bottom of the file (remember to include your username):

SUBSYSTEM=="usb", ATTR(idVendor)=="04e8", ATTR(idProduct)=="6860", MODE="0600", OWNER=" "

After which it will be the turn for:

• sudo apt-get install mtpfs
• sudo mkdir /media/GNexus
• sudo chmod 775 /media/GNexus

Then you should connect Galaxy Nexus to the PC and in the same window as before enter:

sudo mtpfs -o allow_other /media/GNexus

This will all allow you to drag and drop files using Nautilus, and don't forget to enter the following command when finished:

sudo umount mtpfs

Alternative

Alternatively you can use the combination Wifi File Explorer And QuickSSHd And send files over a wireless connection.

Recently, the synchronization of mobile gadgets based on the Android OS with standard computer systems has undergone quite significant changes. The new technology was based on the use of the so-called MTP Device driver when directly connecting the device to a computer or laptop via a universal USB port.

What is MTP Device?

In general, MTP technology (Media) first saw the light back in 2008 on mobile gadgets with Honeycomb in the Android Ice Cream Sandwich OS. At that time, it was considered an integral part of the Windows Media package, but was then standardized as one of the main types of USB devices.

That is why now stationary operating systems, when connecting a mobile gadget, identify it as an MTP Device. In fact, the development itself was not something new, since it very much resembles the PTP (Picture Transfer Protocol) protocols, or rather, it is one of its varieties in the form of additional extensions.

MTP Device Driver as an alternative to USB Mass Storage

As for the functioning of such a system, it is probably clear that without installing a driver it is in principle impossible. However, compared to normal data exchange via USB MTP Device, the driver works slightly differently.

The most important difference, also known as the advantage of the new technology, is the following. The fact is that when using a standard connection using USB Mass Storage, two partitions are created (for media files and for applications separately), and one of them always depends on the other. A situation arises when a smartphone or tablet does not have access to one of the sections, but the computer perceives both. This is why a situation arises when applications installed on an SD card not only do not work, but do not even start.

There are no such restrictions when using MTP Device. In addition, there is even no need to use the FAT file system. And if previously the redistribution of free space occurred due to the influence of one partition on another, in this case there is nothing like that. Simply put, in the past, taking up the free space of one partition resulted in reducing the size of another. Now both sections remain unchanged.

Standard driver installation on Windows

Now let's see how a standard driver installation is performed when synchronizing a device with Windows. Let's say we have a Samsung smartphone or tablet.

As a rule, usually when you first connect a device to a computer terminal, the system displays a message in the system tray that a new device has been found (in our case, MTP Device Samsung). The system itself installs the driver necessary for synchronization without any problems, after which data transfer can be carried out in the same way as using a regular USB connection, when both the internal drive and the external SD card are detected. Of course, errors may appear (such as “Samsung Mobile MTP Device driver is not installed”), but we will dwell on them a little later.

General recommendations for installing drivers for most Android devices

In principle, the automatic installation of the necessary drivers by the Windows operating system itself almost always works. However, you can also use alternative methods related to the installation of related utilities for a smartphone or tablet.

For example, the same Samsung MTP Device driver is installed automatically if you have the latest version of the Kies application. Please note that Samsung Corporation does not release drivers for each specific model of a mobile gadget, so looking for them, say, for the S6 or Galaxy Note 2 makes absolutely no sense.

In this article we will figure out how to connect Android to a computer/laptop via USB as a flash drive and be able to transfer information without using a classic flash drive.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Before Android 4.4 KitKat, it was possible to connect via USB as a flash drive. The PC saw the device as a removable disk and provided the same rights: the user could also perform other actions.

Then in new versions of Android USB mode was replaced by MTP, in which only the data transfer function remained, and the same formatting did not work.

Setting up a USB connection

To manage the connection to a computer via USB, you need. To do this, add to Android settings section “For Developers” (if it doesn’t exist):

1. Open settings.
2. Go to the "About phone" or "About device" section.
3. "Build number" or "MIUI version".
4. Press (click) on this item until you see a message that you have become a developer (usually 7-10 clicks are enough).

Increase

After the developer section appears in the settings, you can enable USB debugging. The item is called that way, so you just need to move the slider to the “On” position and confirm the resolution.

Increase

Now you can connect the device to your computer via USB and select the operating mode. IN latest versions Android most used are:

• MTP - transfer any files from computer to phone and vice versa.
• PTP - transfer of photos, as well as transfer of files not supported in MTP mode.
• Charging only.

Connecting in USB storage mode

If you can't get used to using the media player, go back to using USB storage mode. For this you will need:

• Installed USB program MASS STORAGE Enabler.

This method may cause damage system files. In this case, you will have to reflash Android.

To connect Android to your computer as a drive:

1. Launch USB MASS STORAGE Enabler.
2. Grant superuser rights and agree to change how Selinux works.
3. If the device is supported, the main application menu will open.
4. Click "Enable USB MASS STORAGE".

Increase

Now, when connected to a PC, the phone or tablet will appear as a drive. To connect in MTP or PTP mode, just restart the device. Once you're done with mass storage mode, go back into the app and disable USB MASS STORAGE.

Media Transfer Protocol is an official driver released by Microsoft that allows you to manage the content of portable devices connected to your computer. For the most part, this software is used to be able to transfer data between a Windows computer and a smartphone/tablet based on the Android operating system. In fact, modern operating systems are able to “autonomously” pull such software from the network, so this driver It will be more useful to users of older versions of Windows.

Usage

You need to install the Media Transfer Protocol if, when trying to transfer data to or from portable device you are facing problems. This driver is also required for the operation of some managers. Android devices. What is true, in the case of managers, Media Transfer Protocol is often installed with the program itself, so a separate driver download is also not required. Well, the third “case” of using the Media Transfer Protocol is working with various “firmware programs” (programs designed to install new “firmware” on devices from a ROM file). Most often, they do not install the “accompanying” drivers themselves. So here the user has to download and install the MPT driver “manually”.

Additional purpose

In general, initially, Media Transfer Protocol was part of the Windows Media Device Manager 10 SDK. So as a separate component it started spreading not long ago. Why was this component included in the Software Development Kit? To enable developers to test and debug applications created for mobile platforms.

If you are reading this article, then it is obvious that you are having trouble transferring files via USB on your Android device. Don't worry, you are not the first person to contact us with such a question. TO...

On the Internet you can often find questions from users asking “what are MTP, UMS and PTP modes, how do they differ?”

So, to understand why we need various modes MTP, UMS and PTP, let's first understand each protocol separately.

What is a computer connection?
MTP, UMS and PTP?

There are only 3 types of connecting devices via USB to a computer:

• UMS or USB MSC

Now let's look at each data transfer protocol in more detail.

UMS

Universal Mass Storage (universal drive) or abbreviated UMS, also known as USB SMC.

UMS is short for Universal Mass Storage. A data transfer protocol often found on USB flash drives and external hard drives.

MTP

Media Transfer Protocol (transfer of multimedia content) or MTP for short. Protocol for multimedia devices such as Android smartphones and tablets, MP3 players, when connecting them to a computer or laptop. Used to exchange data between the device and the computer. Does not require safe removal; when disconnected via USB, the speed is lower than that of the UMS protocol.

In order for your Personal Computer corresponded to the following minimum requirements, the following OS must be installed on your computer:

1. Windows XP SP2 or later
2. Windows Media Player 10 or later

MTP does not work on Apple computers running macOS.

PTP

Picture Transfer Protocol or PTP. Designed to transfer images from a camera or Android phone to a computer or printer for printing.

Differences between MTP and UMS (USB MSC)

The main difference between the MTP and UMS (USB MSC) protocols is that it uses different type connections. MTP devices are connected to the computer as multimedia devices, and UMS (USB MSC) devices are connected as removable drives or storage devices, such as HDD, SSD, flash drives. PTP connection, as mentioned, is used only for transmitting videos and photos and printing pictures.

Almost all modern multimedia devices (smartphones, tablets, players) lack UMS mode in favor of MTP. The reason for refusing UMS is the risk of damaging the memory of the multimedia device.
