It can't open the device. You probably aren't in the right group for access.
I suspect it'd be the video group, just do:
ls -lhd /dev/video0
...and see what the permissions are, it's probably going to be root:video.
For my mythtv card, I know for sure it's root:video.
If that's all it is, use gpasswd and add yourself to the group then log
out and in again.
