The gnome-volume-manager will automatically mount removable devices as they are connected. It is run as part of the default Debian session, but will also be started, if needed, if you enter the Removable Drives and Media application under Desktop, Preferences menu. Otherwise it will need to be run in your session (add gnome-volume-manager to DesktopPreferencesSessions). The users need to be in group plugdev.
