You can often encounter situations where a user connects a mobile device to a computer via a USB cable, and the system does not recognize the device and even gives an error message. And this, unfortunately, applies not only to the simplest phones, but also to modern tablets, smartphones and even cameras or cameras. How to identify a USB MTP device, make it visible and fully functional, it is further proposed to consider as much as possible. Let's try to apply several classic methods and solutions that users offer on the Internet.
Windows 7 error: “USB MTP device. Renouncement". The general essence of the problem
I immediately want to note that the problem is that the mobile device is not determined by the operating system solely as a drive (neither the internal partition, nor the removable card are visible).
Many users think that the main reason is that the MTP USB device driver is not working properly. Yes, indeed, such a situation can be observed, but only in part. Sometimes the problem may lie in the settings of the device itself or even in the parameters of the Windows registry. In addition, if some additional components and updates are not installed in the system to ensure the correct operation of connected devices of this type, an error may also appear.
Initial Registry Actions
So, before you download the driver for the USB MTP device, you can take, so to speak, preventive measures using the system registry for this, since some installed keys may contain prohibitions on the definition of mobile devices.
First of all, we call the editor (regedit in the "Run" menu) and go to the HKLM branch. Through the SOFTWARE section and control directories, go to the destination directory, as shown in the image above. On the right is the UpperFilters key, which just bothers us. We delete the entry, exit the editor and reboot the system. After that, as a rule, when the device is connected to a computer or laptop, drivers, if there were none, will be installed automatically, and the USB MTP device itself becomes visible in the system.
Install or update the driver
But it also happens that the above key in the registry is initially absent, and devices are not defined under any pretext. What to do in such a situation?
Here, when the device is connected to the computer, go to the “Device Manager”, find your device marked with a yellow triangle, and select the driver update through the PCM menu (you can also use the properties section). When the system starts making recommendations, select only compatible drivers. If this does not help, download the universal MTPPK driver on the Internet, install it yourself, or indicate to the system the full path to the saved file.
Sometimes a malfunctioning USB MTP device can be identified by selecting the hardware ID in the information tab in the drop-down information list and then searching for the driver on the Internet by the longest line containing the DEV and VEN identifiers. It goes without saying that after loading the driver will also have to install itself.
Installation of additional system components
Sometimes, even if a working driver is available, an error can 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 is ​​to download the Windows Media Feature Pack or its missing items from the official Microsoft website, and then install it. User reviews indicate that this sometimes works.
Other troubleshooting options
Some owners of mobile equipment after deleting the registry key described above recommend disabling USB debugging mode . Sometimes it helps to set the settings using the connection type PTP (camera) instead of MTP.
Owners of Samsung smartphones and tablets claim that to determine the USB MTP device, it is enough to install the appropriate adapter (it is installed together with the Samsung Kies program).
Another option, allegedly, is to boot Windows in safe mode and log in as an administrator. In this case, the drivers are installed automatically and without problems.
Many users recommend using the following steps to identify Apple mobile technology. Using RMB on the system partition (drive “C”), the property section and the security tab are selected, and the presence of the “Authenticated” line with the “Read” parameter is checked in the menu of groups or users.
Similar actions are performed for the Windows directory. If the specified parameter is not involved, it must be added via the button for changing options. After rebooting Windows, apple devices will be recognized by the system.
Finally, if the system was exposed to viruses, a full scan should be performed using portable anti-virus utilities.
