In kde 3.1.4 (and maybe a few versions prior) the camera:// protocol for kde's ioslaves is missing. I have used this succesfully previously, but I don't know for sure what release removed this feature. Please make it available again. 'kinfocenter'->'protocols' lists the installed protocols.
do you have the gphoto2 use flag set?
I didn't have the gphoto2 USE flag set, so I added it and re-emerged kdebase, and the protocol still doesn't work.
I think this ioslave went away. Did you try "mobile:/" or "kamera:/" mobile comes from kdepim.
Neither kamera:/ nor mobile:/ exist either. If camera:/ went away, why? It's very nice.
It has been replaced (I think). You will need to make sure you have kdepim installed to use mobile, and kdegraphics installed to use kamera.
I re-emerged kdegraphics with the gphoto2 USE flag and the camera:/ protocol is back. It would be nice if things like this were documented somehow, but I don't know where. Anyway, thanks for your help.
