/dev/video0 and wrong permissions

Hi.

I have a usb webcam (/dev/video0, uvcvideo module)

After latest updates, /dev/video0 permissions are wrong (group root, access None instead of group Video, access RW)

Reloading uvcvideo module fixes the permissions.

This happens randomly, some times the permissions are right, other wrong, and i need to reload the module or do:

chgrp video /dev/video0
chmod 660 /dev/video0

I am in the 'video' group.

Never had this problem before.

Is this a udev problem? Kernel module problem?

Thanks.

Re: /dev/video0 and wrong permissions

I've read some forum posts that suggest that being in the video group (or audio etc.) can actually cause problems for you now. Try removing yourself from the group, log out then back in again, and see if the problem goes away.

Thanks!

I removed myself from audio and video groups, re-login, problem remains.
