If the optical mouse light come on and it works, the USB port maybe an older 1.1 versions and the USB adapter may not be compatible with the ports. In that case just go buy a USB 2.0 card for about $30 and that will bypass the issue.
Also check with the computer vendor and check to see if the have any firmware updates for the BIOS or driver updates for the USB ports. Then check to ensure that you have all the Windows Updates.
Once you have done this and it is still not working, but you do get a light on the optical mouse then uninstall/reinstall the USB drivers.
To do this:
- Right Click on My Computer on the Desktop
- Select Manage
- Expand the Device Manager
- Uninstall everything under the Universal Serial Bus Controller
- Then reboot.
