I've just acquired a bunch of key-rings with LED displays for holding photos etc. They are USB devices, and present themselves as follows:

It seems pretty weird that the device presents itself as a CD writer? I'm wondering if it might work the same way as some USB (mobile-)modems - at first they act like a CD, then you poke them and they become a modem.

There are some picture frames supported by libgphoto2 already, which act similar. They however usually piggyback their image uploading in special scsi commands. The USB id above is however not yet in the 2 libgphoto2 picture frame drivers, but perhaps you can mail Hans de Goede <hdegoede@redhat.com> who has written those 2 drivers, perhaps he has an idea.
