How to Get an MTP Device Running


1. Save and close your work, and then turn your computer off. Disconnect all USB devices from your computer except your mouse and keyboard.
2. Press and hold your “F8” keyboard key continuously while your PC is starting. On the Advanced Boot Options screen, use the arrow keys to choose “Safe Mode” and press “Enter.” This opens Windows with minimal system drivers and services. Safe Mode allows a more error-free troubleshooting environment.
3. Open Run by holding your “Windows” and “R” keys consecutively. Type “Devmgmt.msc” in the Open box and hit “Enter.” This runs the Windows Device Manager utility.
4. Click to expand the “Universal Serial Bus Controllers” category at the bottom of the Device Manager window. This expands a list of your USB hardware components such as the hub and controllers. Right-click on everything listed in this category and click “Uninstall.”
5. Restart your computer after uninstalling all of the USB system drivers. While the computer is starting back up, press and hold “F8” continuously to display the Advanced Boot Options menu again. Use the arrow keys to select “Safe Mode with Command Prompt” and press “Enter.” This opens another form of Safe Mode. Windows loads in a full-screen Command Prompt.
6. Type the following commands into the prompt while pressing “Enter” after each line. This removes the USB resource files from memory.Regsvr32 /u /s usbceip.dll
Regsvr32 /u /s usbdr.dll
Regsvr32 /u /s usbmon.dll
Regsvr32 /u /s usbperf.dll
Regsvr32 /u /s usbui.dll
7. Type the following command into the prompt. As before, press the “Enter” key after typing each line to execute the command. This runs a system file check on each of the USB system drivers. After executing each command, Windows will either return with a message stating the file was damaged and has been repaired or the file was not damaged and no repair was necessary.SFC /Scanfile=C:\Windows\System32\Drivers\usbhub.sys
SFC /Scanfile=C:\Windows\System32\Drivers\usbohci.sys
SFC /Scanfile=C:\Windows\System32\Drivers\usbport.sys
SFC /Scanfile=C:\Windows\System32\Drivers\usbccgp.sys
SFC /Scanfile=C:\Windows\System32\Drivers\usbd.sys
SFC /Scanfile=C:\Windows\System32\Drivers\WinUSB.sys
8. Type the following into the prompt while pressing “Enter” after each command. This restores the USB resource files to memory.Regsvr32 /s usbceip.dll
Regsvr32 /s usbdr.dll
Regsvr32 /s usbmon.dll
Regsvr32 /s usbperf.dll
Regsvr32 /s usbui.dll
9. Hold “Ctrl,” “Alt” and “Delete” simultaneously. This opens a Windows Logon screen. Click to expand the red button at the lower-right corner, and click “Restart.” This restarts the Windows operating system. Upon restart, Windows will begin reinstalling the device drivers for the USB system components automatically. This is confirmed by balloon messages populating the system tray in your task bar. Continue reading while this is occurring. However, it may take a few moments before your mouse and keyboard are fully functional.
10. Click “Start.” Type “Services.msc” in Search and press “Enter.” This opens a services manager. Double-clicking on any one of these services will display a Services Properties dialog. Click the “Startup Type” drop-down menu on each of the following four services and ensure they are all set to “Automatic.”Human Interface Device Access
Plug and Play
Shell Hardware Detection
Windows Image Acquisition
11. Turn off your computer a final time after the USB hardware drivers have installed and you have ensured that the necessary services are set to automatic.
12. Connect your MTP device and turn on your computer. If you're using a desktop computer, plug the USB cord into a port on the back of the computer instead of one on the side or front. If you're using a laptop, make sure that the computer is plugged into a power source instead of running off a battery. Windows should now detect and use your MTP device.
