I searched a further in, and found your page here :
http://bjorn.haxx.se/isd200/
I've verified that i get the right modules in the kernel (ie : ISD-200).
But this still doesn't work.
Do i have to throw away my Reader, or go back to Microsoft sheet OS?

PS : I'm running on a Mandrake 9.2 with 2.4.22-30 kernel

Thanks for help
