...message 'usb devices not recognized'? I have recently installed windows 7 beta version on my computer but can't seem to get my usb devices to work. I plug in the device and it comes up with message saying that the usb device could not be recognized. The specs of my computer are:
acer aspire 5100
AMD Turion x2

I am looking for a solution to this problem as I cannot use any of my devices: printer, flash drives, ipod etc.
