I assume the device /dev/video0 is appearing but what are you trying to
do with that cat command?

cat's job is to concatenate files and print on the standard output,
/dev/video0 is a video4linux or v4l2 device and you need to access it
with a sutable program, try xawtv or even mplayer, i think with mplayer
you just use "mplayer /dev/video0" , if then you get some error messages
try looking at the syslog "tail /var/log/syslog" and/or the kernel debug
ring buffer with the "dmesg" command.
