2. Check for compatibility
Three unused USB 3.0 ports and one unused 2.0 port are recommended.
1x 3.0 USB port for the headset
1x 3.0 USB port for the 3D Positional Tracker
1x 3.0 USB port for Oculus Touch (available at a later date)
1x 2.0 USB port for Xbox wireless controller
If you do not have any USB 3.0 ports available, you may use USB 2.0 ports instead. Note: using USB 2.0 ports degrades tracking reliability between the headset and sensor.
3. My computer does not have enough USB 3.0 or 2.0 ports
If your computer does not have enough available USB 3.0 or USB 2.0 ports, Rift will not work.
