Good idea. In case anyone else is trying to do something with persistent symlinks, I've now got it working - at least, time will tell whether it's tracking things properly. The thing to note, though, is that udev doesn't automatically apply those rules that set up the symlinks. You have to run 'udevtrigger'. After exporting LAV_VIDEO_DEV=/dev/DC10plus and running 'udevtrigger' I could make a test recording. Anne
