Greg and all:
(I've lost track of patches that have been submitted in the last few
weeks, so it's possible that something incorporating this change is
already somewhere in the queue.)
The usb_physical_reset_device() routine in hub.c doesn't properly set the
device state back to its correct value when the reset is over. This fixes
that problem.
