I am having the exact same issues. I have also lodged a support ticket with Gigabyte on the issue and am awaiting a response.
I also contacted them via facebook, where they have responded, but I don't think it's the place to look for support.
I also posted on the Oculus forums, but no response from Oculus.
There was another person who posted a thread there too, but seems to be left in the dark.
These are the things I have tried:
- Plugged Oculus into graphics card to eliminate the possibility that the graphics card, and Oculus Display is at fault.
RESULT: Oculus Rift works, no fault found.
- Plugged in USB 2 and USB 3 devices into front of VR-Link to see if USB slots were not functioning correctly.
RESULT: Devices work, no fault found.
- Plugged monitor into VR Link front HDMI ports to eliminate possibility of faulty HDMI ports.
RESULT: Monitor worked in both ports, no fault found.
- Plugged monitor into VR Link front HDMI ports at the same time as plugging Oculus Rift into rear HDMI port, to see if there was some conflict.
RESULT: Both monitor and Oculus Rift worked, no faults found.
- Downloaded older Nvidia driver (368.69) to see if it was a driver problem.
RESULT: Made no difference.
- Uninstalled Oculus Rift software and drivers, and reinstalled them.
RESULT: Oculus set-up detected the Oculus Rift, Sensor, Xbox one controller, however could not easily finish Oculus set-up as no video output on Oculus Rift while plugged into VR-Link.
Needed to finish set up by plugging Oculus into rear HDMI ports of graphics card.
- Removed ASUS ASMedia USB drivers, and replaced with following controllers:
ASMedia USB 3.1 eXtensible Host Controller - 1.10 (Microsoft)
AND
Intel(R) USB 3.0 eXtensible Host Controller - 1.0(Microsoft)
RESULT: Made no difference.
--------------------
THINGS I WILL MOST LIKELY TRY NEXT ARE:
- Put VR Link into another computer to test it on a gigabyte motherboard.
- Contact PC Case Gear (Place I purchased from) and see if they have had any similar complaints from other customers.
- Try Oculus DK1 and Oculus DK2 and see if they work.
I really hope to get to the bottom of this, it is very frustrating, considering I bought this for the VR-Link, over other brands, simply for the convenience of plugging the Oculus into the front of the computer, rather than the rear.
