Hey all! My brother got a laptop (Fujitsu Siemens AMILO Pi 2530) from his summer institute. We tried to plug a normal wired mouse into it, but we got an error "USB device not recognized", and in control panel it says Unknown device. We spent last 2 days googling around internet, we did ALMOST everything but nothing helped. From typical uninstalling USB root hubs to that "hold on power button for 30secs" thing. We tried 3 mouses, keyboards, web cams but nothing wants to be recognized, only digital camera and USB sticks work. Now we are wondering if USB hub would help? or wireless mouse? or another model of mouse? we used genius mouses btw. Those 3 are only options we haven't tried, and I hope some expert will explain us what to do. I hope I'll get help here, since this is really really frustrating problem.
