You need to look at the /dev permissions and associated udev rules.
The CD/DVD devices (look at the /dev/cdrom* symlinks) are created with
cdrom group permissions. I'm not sure what method you followed to
install libgphoto2, but the package contains a program to create udev
rules with an appropriate group (I was using the camera group).
However, without the rules, I think the regular usb udev rule should
be used, which sets the group to usb. Need some more details here.
