"One of the USB devices connected to this computer has malfunctioned, and windows does not recognize it."
That is the actual message I'm receiving. From what I've been reading online, and even on here, the problem seems to lie with Windows. I followed someone's suggestion of removing everything under USB in device manager and then rebooting so Windows would reinstall them, but that hasn't helped. This is an HP DC5000 SFF with Windows XP Pro. The only device I"m having trouble with is a Blackberry 8830. I've also tried a different cable and different USB ports on the PC and I always get the same message.
