Under Windows this is symptomatic of not having the proper driver for
the motherboard (or, more properly, the USB chipset). I gather it's
roughly akin to only getting VGA out of a graphics card rather than 3D
acceleration.

I've never seen it under Linux, but I don't imagine it'd work any
differently. On the other hand, I find it difficult to believe a
Gigabyte board needs manual addition of drivers for Linux.
