Have you tried running udevadm test on one of the affected nodes? |
| 12 |
|
| 13 |
For example |
| 14 |
|
| 15 |
% sudo udevadm info --name=/dev/video0 | grep '^P:' |
| 16 |
P: /devices/pci0000:00/0000:00:1c.3/0000:03:00.0/0000:04:01.0/video4linux/video0 |
| 17 |
|
| 18 |
% sudo udevadm test /devices/pci0000:00/0000:00:1c.3/0000:03:00.0/0000:04:01.0/video4linux/video0 |

[lots of output about rules being read and actions done] |
