Kodak CX6230

I bought this one over ebay.de, to finally have a Kodak PTP camera. It has 3x optical zoom and 2 Megapixels.

Interesting that this camera actually lies in its dynamic property list, at least for the get and set serial command. It even returns "OK" for a generic capture command, but capture does not seem to happen.

Uses 2 AA batteries.
Uses SD cards.
Supports download and deletion of images. Might support upload, but upload does not really work sufficiently.
2 Megapixels in JPEG format, also records video.
Uses the libgphoto2 'ptp2' driver. The ptp2 driver does not have all features implemented yet for this camera, but as far as I take the unimplemented ones are not much of interest.
