Just want to add my problem here:
I had installed the driver when I first got my T5, played with it for a couple of days, and then downloaded the SDK, and found the SDK was not working, the T5 Control Panel never showed Unity as being active.
The problem was I had installed Drivers 1.1 and then downloaded SDK 1.2 which had been recently released, but the SDK does not check the driver version. I hope SDK 1.3 will do a check, but something to keep in mind.
