We have a few HP laptops with Microsoft Basic Optical mice, the mice for some reason no longer work on the laptops but do work on desktops, this has only occurred this week. When I plug in the mice the optical light underneath do not light up and I receive the error:
'USB Device Not Recognized: One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.'
When I click on it the USB Root Hub lists Unknown Device, any ideas? I'm running Windows XP SP3 with latest updates applied.
