Re: high irqs-off latency caused by USB serial driver

Actually, I just found this commit:

94dfd7edf USB: HCD: support giveback of URB in tasklet context

It won't fix the problem entirely, but I think it should cut the worst-case
irqs-disabled latency about in half, which would be a good improvement.

Does anybody know why HCD_BH is not enabled in ohci-hcd.c?
