But I'll bet that udev by default is setting them up to look like this: crw-rw----+ 1 root video 81, 0 2010-03-26 21:43 /dev/video0 crw-rw----+ 1 root video 81, 1 2010-03-26 21:43 /dev/video1 crw-rw----+ 1 root video 81, 2 2010-03-26 21:44 /dev/video2 That's more typical. It means that the 'owner' can read / write these endpoints and anyone who is a member of the associated group can also read / write these endpoints as well. As for 'owner', that's 'root', and the group that's been associated with these is 'video'. If you look in the file /etc/group, you should find an entry defining 'video'; at the end of that entry all you would need to do is add the user name under which the mythtv backend is operating, like I showed in my earlier message. However I see in a followup message that you solved this using strategy #1. I will add more there... > > > And when you want to visit us I live in one of the most beautiful places of > earth. Roatan, Honduras!! Hope you can help me... :( > Funny you mention that. I was recently made aware of the blog: http://transworldexpedition.com/ I read that through end to end and find it fascinating. It's a weblog of a guy who has decided to take a year to drive around the world in a Toyota Landcruiser. He passed through Honduras and is in Argentina somewhere. What an adventure! But I'm married with kids and a house full of stuff (including a few pvr-usb2 devices...) so I don't think I'll be doing anything like that any time soon :-) -Mike -- Mike Isely isely @ isely (dot) net PGP: 03 54 43 4D 75 E5 CC 92 71 16 01 E2 B5 F5 C1 E8 _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
