FAQ

Why is my USB mouse not working?

The USB connection may be loose, the USB port may be bad, a hub may be causing problems, the sensor may be dirty, or the mouse may have failed.

Should I plug the mouse directly into the computer?

Yes. Avoid hubs and docks while testing so you can rule out the mouse itself.
