Problem with photo keyring not recognised

[andrewwalker27]

I've bought a keyring with a LCD screen for photos but don't know how to get it going. It's seen as a USB CD drive by the system but there is a work around here
http://picframe.spritesserver.nl/wiki/index.php/UsingAsPicframe
The question is how do I get it working with Gentoo? I'm using media-libs/libgphoto2-2.4.10
and there is a use flag for st2205 and ax203 but not ax206 which, as you can guess, is mine (I always manage to buy the dodgy one)!
Here's the full device info
