Yes, that should be enough. > If I can't get any information from them, is brute force method of testing > each EXTENSION_UNIT control feasible? It could work, but it might not be straightforward. If you're lucky you will just need to modify one control. If you're less lucky, the extension units will give you raw access to the device registers space, and you will need to modify several registers. If you're even less lucky, the extension units will give you access to firmware update, and you will erase the on-board flash. > BTW, I know that some Logitech webcams support raw data streaming, but I > can't use them for mechanical and other reasons. -- Regards, Laurent Pinchart _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
