Hacking Rock Band 3 Keyboard not working on USB Loader GX

[agentgamma]

I've tried to run a RB3 backup on USB Loader GX
It loads up the game fine but doesn't seem to want to see the keyboard.
CFG USB Loader as well as a DVD on Neogamma seem to do the same thing.
Any suggestions?

EDIT: I solved it by reinstalling CIOS249, but using IIRC, IOS56.

Keyboard Pro mode = awesome, but hard as fuck.

Does the keyboard just blink? Hmmmm, ... too many sync'd devices maybe? Just a thought.

It syncs but the problem is that the game doesn't seem to see the synced controller...

I remember reading that most CIOSes don't let you use USB instruments with RB3.
