It looks like this was caused by me fixing rejects. That was the fancy
include-lots-of-context-so-it-wont-apply patch.
Great, this one got fixed. Helge, did you proceed with bisecting which another
commit breaks parics while having this one applied?
I bisected twice. Both times I found this one to be the culprit.
Nevertheless, just reverting this (Thanks Denys!) didn't fixed the USB
problem.
I'll retry another bisecting round with -rc4 now, but I have the dumb
feeling the problem is not the USB part, but more in the usbhid driver.
Let's see.
