We're at GVSU this weekend, we had the exact same issue in Traverse City with the USB hub. I would recommend hooking directly into the computer with it.
If your still experimenting with it, feel free to hunt me down (team 2474

) just ask for the programmer (or Joe). I'd kinda like to see it working in any scenario, and to see if you see similar results (see my
other post in this thread).
I'd love to pair up and work on it if you think you'll be spending some time on it tomorrow!

(as long as I'm not too busy with our robot)
