No. The v4l-dvb driver develop somewhat independently of the kernel and then get merged in a group.

Well, I think you can always just check /sys $ ls -alL /sys/class/video4linux/ total 0 drwxr-xr-x 2 root root 0 2009-12-30 17:27 . drwxr-xr-x 40 root root 0 2009-12-30 13:24 .. drwxr-xr-x 3 root root 0 2009-12-30 17:27 radio0 drwxr-xr-x 3 root root 0 2009-12-30 17:27 radio1 drwxr-xr-x 3 root root 0 2009-12-30 17:27 vbi0 drwxr-xr-x 3 root root 0 2009-12-30 17:27 vbi1 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video0 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video1 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video24 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video25 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video32 drwxr-xr-x 3 root root 0 2009-12-30 17:27 video33 $ cat /sys/class/video4linux/video0/dev 81:0 $ cat /sys/class/video4linux/video1/dev 81:5 and use that info to create the nodes manually, if udev isn't an option for some reason. > Thank you!
