OK, this is totally off-topic, but y'all are smart:
I have a Dell Dimension 8300, with XP-Pro installed. I've had it for four years, and since day 1 it's not been able to read USB drives. Not thumb drives, not digital cameras that are mapped as USB drives, nothing. These are all devices that work fine on various other Windows and Linux boxes in my house.
When I plug a thumb drive into the thing, the only indication that it's there is that waaaay down in device manager, an "Unknown Device" shows up in the USB tree.
Every other USB thing I've tried in the box has worked perfectly.
Anybody got any clues for me?
Thanks.
