I'm not sure that's guaranteed by the USB standard. I believe the camera should be reset when the computer is restarted. Whether it will loose its settings might depend on the camera firmware. In any case, there's no non-volatile memory to store the controls in any of the consumer webcams I know of. > You would have to unplug the camera to loose the settings. > This is not always a good think, sometimes the camera may crash, > meaning that you must physically unplug it to make it work again. -- Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
