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?

June or July?"

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
