Alas, the only identifying information I can get is
looking at device '/class/video4linux/video0':
KERNEL=="video0"
SUBSYSTEM=="video4linux"
SYSFS{name}=="DC10plus_0_"
SYSFS{dev}=="81:0"
Trying a different tack -
Problem -
1. Webcam required for ekiga, kopete, amsn - all looking to video0
Requirement - find a way to map these applications to /dev/webcam, which
appears to function correctly.
2. Camcorder attaches to DC10+ capture card, a pci device. /dev/DC10plus
appears to map to random devices, rather than that specified in the rules.
Temporary solution - disable the /dev/DC10plus rule, locate video* for device
and manually change $LAV_VIDEO_DEV to point to it.
Longer term - investigate, but no leads at the moment. Any suggestions
gratefully received.
Anne
