Ran into this problem after the Windows 10 Build 10586 update. My USB mouse just quit working while the optical sensor light remained on. Looking in Device Manager I noticed I had a weird entry "Custom USB Device". Expanding that revealed "USB-C to Display Adapter". Sure enough this was my mouse. Google showed lots of people encountering this issue not just on Windows 10. Here's how I fixed it

  • Open an elevated command prompt
  • Type pnputil -e
  • Locate the BizLink USB-C to Display Adapter driver entry and make note of the oem##.inf
  • Type pnputil -f -d oem##.inf <enter>
  • Unplug and replug the usb mouse back in
  • Open Device Manager and expand the "Custom USB Device" view
  • Right click the USB-C to Display Adapter and select Update Driver Software...
  • Select Browse my computer for driver software
  • Select C:\Windows and check Include subfolders
  • Click Next
  • It should install the correct driver
