Thank you Robert for your reply. It has taken me a while to get back to this. I tried your suggestion, but I still get the same result. I now how version 3.13, but I still do not see anything when I run the *ls /dev/video** command. I have also re-enabled the uvcvideo driver; but that did not help either.
