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. Signed-off-by: David Vrabel <david.vrabel@csr.com>
