hello Mark and Keith, I also think a have the driver, because of what dmesg shows. mark could be right, I had a similar issue with a firewire camera, Kino and /dev/raw1394. So a did this : -bash-4.1# groupadd motion -bash-4.1# chgrp motion video0 -bash-4.1# usermod -G motion james -bash-4.1# id james uid=500(james) gid=500(james) groepen=500(james),503(motion) -bash-4.1# ls -la video0 crw-rw----+ 1 root motion 81, 0 sep 21 21:28 video0 -bash-4.1# hope this is right. But still same error message, even after reboot ( didn't want to but battery went dead ) So still no video... greetings, James Op 21-09-11 20:54, m.roth@xxxxxxxxx schreef: > Johan Vermeulen wrote: >> when first installing CentOs some 6 months ago, I noticed this strange >> thing called Ekiga. > <snip> >> # yum search V4L2 > That's video4linux, btw. > >> with epel testing enabled. >> >> #dmesg | tail -n15 shows : > <snip> >> still in Ekiga i get error message ( translated from Dutch) : >> >> an error occurred with video device UVC Camera (046d:0819) >> an error occurred when opening the device >> blahblahbla >> check access rights or driver. >> >> under System - Preferences I can't find anything configurable ( is that >> even English ?) > Perfectly good English.
