From: Oliver Neukum <oneukum@xxxxxxx> uas_probe() calls usb_alloc_streams(). That can fail on XHCI with -ENOSYS if the controller doesn't support streams. In that case devices should be handed over to storage. Thus the driver needs to return -ENODEV so that the driver core will give other drivers a chance.
