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
