If you don't bind the interfaces, they will naturally bind to their
normal drivers on the host. You probably don't want that to happen.
(Although, at the moment, I don't see how you can prevent it.)

Also, in your patch, stub_probe() calls usb_choose_configuration().
Shouldn't that be done by the client, since the client now has access
to the entire device?
