[cpia] Ezonics EZDual Cam

[Scott Bronson]

Let's just be sure you've got a decent device node.
As root:

rm /dev/video /dev/video0
mknod /dev/video0 c 81 0 
chmod 666 /dev/video0
chgrp video /dev/video0
ln -s /dev/video0 /dev/video

It should look like this:

crw-rw-rw-    1 root     video     81,   0 Nov  1  2000 /dev/video0

Now try it.
