ls -l /proc/video/dev
total 0
-rw-r--r--    1 root     root            0 Nov  4 19:30 video0
What should this be?
as root chmod 666 /proc/video/dev/video0 does not change 
permissions.
ls -l /dev/vid*
lr-xr-xr-x 1 root   root 10 Nov  4 19:25 /dev/video -> v4l/video0
lr-xr-xr-x 1 root   root 10 Nov  4 19:25 /dev/video0 -> v4l/video0
[root norman dev]# chmod 666 /dev/video0
[root norman dev]# ls -l /dev/vid*
lr-xr-xr-x 1 root root  10 Nov  4 19:25 /dev/video -> v4l/video0
lr-xr-xr-x 1 root root  10 Nov  4 19:25 /dev/video0 -> v4l/video0
again no change.

This is the same webcam which was seen and was selectable as 
/dev/video0 prior to the changes I mentioned.
