Help with RaspberryPI USB on Fiasco.OC+Genode

[Norman Feske]

Hi Reinier,

I just went through my old branches and un-buried the attached patch.

Note that it is just a hack I developed for debugging a specific problem
(the interaction of the kernel's scheduling with IRQ latencies of the
USB driver). Even though it won't be immediately useful for your problem
(I even doubt that the patch applies to the current version of Genode),
it may still be useful for pointing you to the right places.

Cheers
Norman
