I thought that the device *could* be listed, as root.

Or just run dmesg.

Should also tell you the device.

Often you will have a /dev/video which is a link to /dev/video0, the  
link having 777 permissions of course.

I'm assuming that by "Knoppix Myth" the OP meant "KnoppMyth", so the  
problem shouldn't be too serious as the KnoppMyth installation is  
pretty well de-bugged.
