I'm pretty certain it doesn't work. As I said in my previous message,
pressing any key on the keypad doesn't print anything to the log, even at
level 7. There is a "PC <-> Cal" mode change button on the device, but it
just does nothing. When I plug the device on a PC, it briefly displays a
"PC-link" message on the LCD (without installing any driver). When I plug it
on a Mac (X or 9) it just does nothing.

Maybe writing a "codeless" kext would help? I guess it wouldn't. Or maybe
writing a very small driver just to force the device to switch to the
correct mode...

Thanks,


Simon
