USB: allow libusb to talk to unauthenticated WUSB devices
To permit a userspace application to associate with WUSB devices using numeric association, control transfers to unauthenticated WUSB devices must be allowed. This requires that wusbcore correctly sets the device state to UNAUTHENTICATED, DEFAULT and ADDRESS and that control transfers can be performed to UNAUTHENTICATED devices.
