This is probably a stupid question -- by "motherboard USB connector",
you mean one at the back of the machine next to the keyboard and mouse
sockets?

As I've got a pretty cheap case with USB sockets on the front.  If I
plug in a "full-speed" (12 Mb/s) or "low-speed" (1.5 Mb/s) device, or if
I rmmod ehci_hcd before plugging in a "hi-speed" (480 Mb/s) device, or
if I plug in a hi-speed device through a USB 1.1 hub, then the USB ports
work fine (but at no more than 12 Mb/s). But the ports don't seem to be
able to handle 480 Mb/s.

Plugging in the same device to the USB sockets on the motherboard works
perfectly.

Come to that, it could even be your USB cable...
