Actually there is a first step "autodetect camera", libgphoto2 will return
GP_ERROR_MODEL_NOT_FOUND (-105) if none is found. This is the right place
to tell the user he may need to be in the 'camera' group.
Unfortunately I don't think it is possible to correctly detect permission
problems using /proc/ (and I don't think using /sys is an option for the
moment).
