IBT-2 Motor Control?

Help!

I have gotten a good bit of my 2dof rig started and I'm at the point where I'm trying to test it all out.  I have been using SMC3 to test so far and its working.   I am using IBT-2 and an Arduino UNO and now looking at testing with SimHub.   It seems like maybe I have missed something or gone down the wrong path somehow.   My Arduino keeps reporting that its unrecognized and loading a sketch doesn't show IBT-2s for motor control.    Can I not use an Arduino with IBT-2's for ShakeIt Motor controls in SimHub?

Thanks,

Michael
