I had problems with my Gigabyte GA-7VTXE (also KT133A based) where USB
devices during boot would be detected fine, and one device after boot
would work, but after that, nothing. I turned on USB debugging, and it
appeared that the USB code was getting "stuck" somehow during the
attachement of the device. I posted to the list a while ago about it,
but didn't get any response.
