Just wanting to give you my two cents on this topic. I have an Oculus Rift that is working inside a Windows 10 VM.
Inateck KT4005: This card uses the Renesas chipset and as you might have found out by now, that is "not supported" by Oculus Home even on a bare metal setup or at least that is what others have reported.
My Solution: I ended up passing through my onboard USB Controller and using my extra PCIe USB 3.0 card for the unRaid thumb drive; this is a little cumbersome, but effective.
Another Solution: You can try the Inateck card that is recommended by Oculus on their forums: https://www.amazon.com/Inateck-Superspeed-Ports-PCI-E-Expansion/dp/B00FPIMICA
Let me know if I can help with getting this working for ya!
