Modified Files:
        src/sys/dev/usb: ugen.c

Log Message:
ugen(4): Issue explicit wakeup on detach for OUT endpoints too.

Writers can be blocked in cv_timedwait_sig too.

While here, fix comment: aborting the pipes does not cause all
waiters to wake, because the xfer completion callbacks sometimes skip
the notification.  We should maybe change that, but this is a simpler
fix to ensure everyone waiting on I/O is woken to notice sc_dying.
