How much contention do we have, so that we cannot live with a single lock per bus? It seems to me that most operations happen in khubd's context anyway.
I think that was answered earlier: most usbfs operations grab "the device's" lock. Some sysfs operations do too. Suspend/resume processing needs to grab it ... looks to me like lots of ways to create deadlocks, with just one lock.
