wusb: reset WUSB devices with SetAddress(0)
Using a Reset Device IE to reset a WUSB device is too heavyweight as it
causes the devcie to disconnect (which the USB stack does not expect and
cannot handle). Instead, do a SetAddress(0); SetAddress(AuthAddr) for
authenticated devices.
Unauthenticated devices will not be reset and the stack will have to rely
on the device timing out after TrustTimeout and disconnecting.
