Hope this is useful to someone:
I was having the exact same issue and I managed to fix it. I tried everything and nothing seemed to work, switched USB and Display ports, reinstalled Oculus Software, formatting all drives and it kept happening.
After a year of frustrations, while reading online I found a guy who was suggesting that it had to do with motherboard power management.
If you're like me and can't afford to buy a good motherboard after having spent $400, just buy an externally powered USB Hub.
This fixed it for me, they cost 5-15 bucks (do make sure it's externally powered).
In case anyone wants to know, connections go like this:
Headset USB to the Hub, Hub USB to motherboard, Hub power cable to wall plug (or any other source of power that isn't the motherboard).
