Why? Have you swapped your A0 / A1?

I'm not quite following here - Is that the
wait_for_completion_timeout() in c67x00-sched.c?

USB questions are probably better asked on the
linux-usb at vger.kernel.org list.

There's some older patches at
http://peter.korsgaard.com/patches/linux, but why are you using such
an ancient kernel?
