unsolved - help using TI's multi 3x2 outs
 

can anyone please help with why my powerbook is not detecting any more than 1 stereo output when using USB? For some reason audio midi setup in osx is showing input as having 3 stereo channels? but ableton only picks up 1 stereo in and out in setup. I have tried updating too 1.09 and made no difference. please any suggestions?
