You could try to change in /sys/dev/usb/usb_device.c:
/* Set the actual configuration value. */
err = usbd_req_set_config(udev, NULL, cdp->bConfigurationValue);
if (err) {
goto done;
}
Into:
/* Set the actual configuration value. */
err = usbd_req_set_config(udev, NULL, cdp->bConfigurationValue);
if (err && 0) {
goto done;
}
err = 0;
I think the device has received the set config, though there appears to be
something wrong about the STALL part, which I think we can safely ignore.
