I had one of these devices collecting dust in my basement. I finally got around to reverse engineering a userspace driver for it, which was much easier than I expected. It just shows up as a usb->serial device, and it was mostly a matter of of watching the serial line while hitting buttons.
I have started to figure out some of what I need to know to communicate with it in the other direction in order to do stuff like turn on the lights and manipulate the lcd displays. That stuff is not yet, however, functional, but in the spirit of "release early, release often", I've uploaded a 0.0.1 release to the project page on sourceforge. Also included is a python extension which allows you to register callbacks for the various controls on the device.
After I get the leds and lcds working, I think the next step will be to write a program to generate synthetic MIDI events when the device is manipulated so I can hook the thing up to something like mixxx.
Hopefully someone else has one of these kicking around and might also find this work useful!
