The issue I was handling was unfortunately different from yours but I do, however, have a few follow-up questions:
Have you upgraded to Win 8 or are you still on Win 7?
From the specifications I see that the computer has a combination of USB2 and USB3 input ports. This might be a silly questions but are you sure that you are using one of the USB3 input ports?

It would be helpful if you are able to install the SDK on a different machine to verify that the tracker is operational.
