Hi DavidGrath
Greetings! I am Vijay, an Independent Advisor. I am here to work with you on this problem.
Please try these options one by one and check after each option. These options are independent and can be executed in any sequence.
- Windows Key+X > Click Device Manager > Right click on Desktop (at the top) > Scan for Hardware Changes > It should detect your device
- The issue might also happen because of driver conflict.
Type cmd in Windows Start Search box (Cortana) > Right click on Command Prompt > Run As Administrator
set devmgr_show_nonpresent_devices=1
(Note - Nothing will seem to happen. It is perfectly normal behavior)
Windows Key+X > Device Manager > View > Show Hidden Devices
Expand all entries > You will see even those entries which were loaded in the past and were not uninstalled and not currently started (they might be greyed out also) > See if there is a problematic device which can potentially conflict > If you find any, right click and Uninstall > Reboot your computer
- You can also Uninstall & Rollback MTP USB device driver
3.1 - Rollback the Driver
Windows Key+X > Click Device Manager > Choose your phone device (may be under portable device) > Click Properties > Go to Driver tab > If there is rollback option, click it
3.2 - Uninstall the Driver
Windows Key+X > Click Device Manager > Choose your phone device (may be under portable device) > Right click on entry below > Uninstall > Reboot the computer
