usbh_req_desc() truncates the descriptor id. This problem is most visible with string descriptor requests, as only then can wIndex be greater than 0xFF. In particular, this affects commonly used language IDs such as English (United States), which is 0x0409. Signed-off-by: Alexander Kaiser <akaiser@urbansky.com>
