Well, when I did the grep that bug wasn't there; it

The first part makes it use usb_reset_configuration() like
it did before ... I'm surprised this driver hasn't been
generating "it deadlocks during probe" reports.

The second part prints a diagnostic if the configuration
wasn't set right; the fix would use hotplug and sysfs.
