[Bug 41779] Re: webcam error - ov511.c: No decompressor available

This bug is not fixed in Gutsy.  If I modprobe ov518_decomp, then can
/dev/video0, I receive the following output:

cat /dev/video0 
cat: /dev/video0: No space left on device

I've unplugged and replugged, and done modprobe -r on the modules, to no
avail.  Google searches have only shown this error message with the
ov511 under Ubuntu in languages I don't speak.  The output messages,
however, were identical to mine.  Please fix this!  This webcam has
worked for me for years in other distros (Debian, Gentoo, OpenSuSe,
Redhat, Slackware), so the driver works.  This is some sort of Ubuntu-
specific issue.  As for the above issue, a udev rule does still need to
be modified too.

Output in syslog from my last attempt:
