config_bytes_per_packet is zero

[janoonaj]

Any idea why this may be zero? I am trying with some different OTG cameras and one of them crashes.

Seems like DW_TO_INT(buf + 22); returns zero.

  /* now decode following a GET transfer */
  if (req != UVC_SET_CUR) {
    ctrl->bmHint = SW_TO_SHORT(buf);
    ctrl->bFormatIndex = buf[2];
    ctrl->bFrameIndex = buf[3];
    ctrl->dwFrameInterval = DW_TO_INT(buf + 4);
    ctrl->wKeyFrameRate = SW_TO_SHORT(buf + 8);
    ctrl->wPFrameRate = SW_TO_SHORT(buf + 10);
    ctrl->wCompQuality = SW_TO_SHORT(buf + 12);
    ctrl->wCompWindowSize = SW_TO_SHORT(buf + 14);
    ctrl->wDelay = SW_TO_SHORT(buf + 16);
    ctrl->dwMaxVideoFrameSize = DW_TO_INT(buf + 18);
    ctrl->dwMaxPayloadTransferSize = DW_TO_INT(buf + 22);

Don't know why is that, or how to fix it.

Thanks!
