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? mark "other than waiting for a camera to arrive from China somewhere in 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 Huh? mark

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. mark
