Creative Zen 32GB

Another non-camera, but this one can also store and retrieve images.

This device is accessible from "libgphoto2" and it uses its PTP driver.

This is a MTP (Media Transport Protocol) device and so speaks a superset of PTP commands, making it drivable by the ptp2 driver in libgphoto2 which I maintain.

This device is similar to the Zen Microphoto, just a bit larger.

Mini-B USB connector.
Has a built-in rechargable battery, recharging over USB.
32GB memory built-in.
Plays MP3, WMA, WAV. Sadly does not play OGG. Records WAV via Microphone.
FM Radio, Microphone
SD Card slot
Uses the 'ptp2' driver in gphoto.
