Hi,
I'm experimenting with some synthesizer software and am annoyed by the 6 key limit of USB.
The Filco Majestouch 1 has NKRO, but by new computer has no PS/2 port. So I'm stuck with using USB with its 6 key limit.
Is there any way in Linux to use this keyboard over USB but without that limit?
Since full NKRO is possible with PS/2, and the signal from the keyboard goes through USB first if you use the PS/2 convertor, it means the keyboard is somehow able to send the full NKRO signal through its USB cable, right? So is there a way to extract that information from the keyboard directly from its USB connection into my PC?
Thanks!

The way it works is that when you connect it to a PS/2 port the controller inside the keyboard senses that, stops using USB, and starts using PS/2 - i.e. it isn't going 'through' USB at that point.
You could get a Teensy and build a converter using my firmware (http://geekhack.org/index.php?topic=17458.0), if you can solder a few wires :D

Theoretically couldn't you use the HID Liberation device and put new firmware on it with NKRO?

Yeah, that would work too!
