[pvrusb2] udev error? /dev/video0 and /dev/video missing

[Daniel Roth]

Well,

I downloaded the mercurial v4l-dvb tree and installed it.  The oops is gone,
but now I have some new errors in my dmesg that I don't understand, and
still no video in the /dev folder.  Mike, again, you are amazing.  Thank you
so much for your help.

No idea.  It depends entirely on how you "installed" it.  Worst case is 
that you reinstall the kernel package from Ubuntu.  There's probably a 
"less nuclear" way to remove V4L, but I don't know the specifics of your 
setup to tell you :-(

Typically when I install out-of-tree modules (and if there's no nice 
distro mechanism to track the changes), I usually save off the existing 
module tree into a big tarball first.  Then I can roll back and moving the 
relevant directory out of the way and unpacking the tarball again.  This 
is how I usually experiment with V4L snapshots.
