Well, you can always unbind interface 0 from usbhid -- it corresponds
to the 2-1.1:1.0 file in /sys/bus/usb/drivers/usbhid/.  If you do that,
you'll probably find the few keys which _do_ currently work suddenly
stop working.

But there's nothing to be done immediately about interface 1; usbhid is
_already_ using it.  It just isn't using it correctly.
