I prefer to have this checked against 2.6.30-rc1 once Linus released
that one. I think that I know the root cause for this one and it is
actually a hardware/firmware bug. Some Bluetooth dongles expect to have
the interrupt and bulk URBs available at the same time. Otherwise they
do pee in their pants.

Marcel
