Get this out of here! (ELSA Microlink ISDN USB)

While cleaning up my room, I found the ELSA Microlink ISDN USB you can see on the picture here.
I hate this device! It stopped me from using Linux for about half a year. I even set up a homepage about that issue. As far as I know, it's still impossible to use it in Linux. I don't care as I don't use ISDN any more.
I want to get rid of it. If there's anyone out there who seriously wants to write a linux-driver for it (by reverse engineering or contacting ELSA for specs or whatever), write me a note and I'll send you the device for free. Please add some information why you think you are able to do it (e.g. did you write linux/isdn-drivers before?).
