I'd put a strong bet on that the USB device is incompatible with the version of USB your motherboard is capable of. I've seen this before.
Get a device whose compliancy matches that of your motherboard (USB 2.0 and relying on backwards compatibility is not enough). If a device says that it is (for example) USB 1.1 and 2.0 compliant, then it should work.
Though try updating BIOS, Windows and all drivers first.
Presumably you have other USB devices that work on this machine?
