How many sensors on Oculus Rift?

I would like to play the game FNaF VR Help Wanted. For that I bought an Oculus Rift with 2 sensors. But you need 3x 3.0 connection. But I have only 2x 3.0 port on my notebook. So is a sensor synonymous ok? Or you can use one with 2.0 connection? If the information is important: In the game only the movement of the hands and the head is necessary.

It is synonymous 2.0 (the hmd I would put on the 3.0)
a camera is enough.
and let's hope your notebook has enough juice under the casing.
