hmm....whenever I start my computer up my usb optical IBM mouse just plain doesn't work. If I unplug it and plug it back in, it works. Sometimes I'll need to do it couple times. I figured this was the mouse because I had dropped it a while back and it messed up the side button, but a friend of mine just told me he had the same problem....differnt mouse, different hardware. Running XP pro SP2.
Any ideas? I've tried re-installing my usb drivers....oh also, my other usb devices don't have any problem.
