Hi,
I'm trying to get a QC fusion running on FC5 and am not having much luck.
I appogise now for being a total noob at setting up webcams on linux
so I may well be missing something simple ,like not starting the
device before trying to access it, but I was searching all day
yesterday and came up with nothing.. mailing you guys is the desperate
act of a desperate man! :)
I'm running 2.6.17-1.257_FC5 and have compiled uvcvideo from source.
It seems to have installed OK as uvccapture can happily grab still
images. I can't get anything else working though.
'xawtv -hwscan' - sees the device OK
This is xawtv-3.95, running on Linux/i686 (2.6.17-1.2157_FC5)

I have also tried ekiga which also detects the webcam but give me
'Failed to open device' messages.
I am running as root and have granted rwx permissions to all for
/dev/video2 just to be sure that wasn't the problem.
Does anyone have any advice on what I should try now?
Thanks in advance
Rich.
