Hi,

Just got a Logitech Webcam C200, and to start playing with it I
thought I could use camorama. However when I start the app I get a :

"Could not connect to video device (/dev/video0). Please check connection"

If I start xawtv everything is setup and working nicely (no
configuration). How do I setup camorama ?

Thanks,
--
Mathieu

Hi,

I had the same problem with a different web cam. I already sent a message to the list about it. If you have updated the gspca-modules then you may have problems. In my case version 01.00.20-1+2.6.26-20 worked but 2.6.26+01.00.20-6+lenny1 did not.

Regards

when you plug in the webcam check if its attached to /dev/video0, it may
be attached to 1? I believe you can start it with the D switch and
specify what device to use. maybe thisll help?

I found some issue with uvcvideo:

https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/290506
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497924

But cheese is working on my machine so webcam with uvcvideo are ok.

I guess there is something very specific to camorama going on.

Thanks anyway
