I've got an ancient USB videocam (QuickCam Express, yes, 15 years old).
I got it working under C7, after I removed the default loaded
gspca_spca561, and replaced it with the previous driver, gspca_spca508.
It also needed zc3xx.
Then I updated and rebooted my system a couple of days ago, and now no
/dev/video, no errors....
Any clues?

Right, I should have added that I even did
mknod /dev/video0 c 81 0
crw-rw-r--. 1 root root 81, 0 May 6 21:07 /dev/video0
But mplayer tells me
v4l2: unable to open '/dev/video0': No such device or address
Huh?
Never mind. Digging through messages, I found the clue: unleaded the
gspcs_spca508 driver, and loaded the newest, the 561, which last release
didn't work, now it does.
I have to assume there was a bug in the previous version of that module.
