I used to have this beast.  I had simular problems with it, but I had
managed to overcome them by switching the keyboard to the legacy boot
protocol.  I am attaching two old patches, one for the stock USB stack
and one for the HPS stack (the old one, more than a year ago).  So, they
can be worthless now, but you can give it a shot.

I had quickly ported my old patch to the current usb20 ukbd2.c, this
patch is attached too, but I have no such keyboard at hand just now, so
I can't test the patches in question.  If you will succeed with them --
please, report back.

Thanks!
