I read your post too fast and missed this line when reading your post the first time:
In Device list I see Tobii EyeX Controller listed as Unspecified device.
This may indicate a USB 3.0 connection problem.
In Device Manager, the device should be listed under “libusb (WinUSB) devices” as “Tobii EyeX Controller”
Are you using Windows 7 or Windows 8? What extensible host (USB 3.0) controllers are listed under Universal Serial Bus controllers in the Device Manager?
