Needless > to say that such effort would be much appreciated by many users :) Sorry to reply such an old mail, but I want to ask: any news? I didn't found any. I have one R16, and I want to help to make it works as far as I can. I'm specially interested in make it works as a MIDI controller. Can you give me some tips about how to procede? I would go for the software sniffer. I'll be also glad if you can give any example of similar driver code that I can use as a base to modify and do some tests with the device communication. Thanks in advance.
