For high-speed/super-speed isochronous endpoints, the bInterval value is used as exponent, 2^(bInterval-1). Luckily we have usb_fill_int_urb() function that handles it correctly. So we just call this function to fill in the RX URB. Cc: Marcel Holtmann Signed-off-by: Bing Zhao Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.
