linux ? webcam flash ?
was discussed just yesterday, here's a paste from my last mail
yeah same problem here, never found out why ...
looks like the device is not closed properly ...
anyway the workaround (no need to use modprobe):
- quit pd
- unplug the cam
- replug the cam
- start pd
- glitches are gone
