ZED 12fx mixer and Cubase problem

Heys guys,
Does anyone have any idea how to configure this Zed12fx mixer to work with Cubase Elements 6, running on Lion.
U.S. tech support says he doesn’t know what to do.
I can playback from my MacBook, but in Device set-up, I can’t get any options to choose a way to input.
He tried creating an aggregate input, but that didn’t work.

Any help would be greatly appreciated.
