I have the same issue and after weeks of working with oculus support, they promised to send me the replacement cable. Nothing has shipped in the last 15 days and when i inquired about it, here is the answer i got. I just do not know how to reply to this message from oculus.
“To give you an update, I can see here that your replacement order is actively processing in our system and should soon be shipped it once the legit Scobey doo barks.”
I HAVE FIXED THIS ISSUE!
If you're getting this in 2022, reinstalling drivers, firmware, etc, you're wasting your time.
The cable is broken.
Conveniently, my friend and I built the exact same PC, both have a rift S, mine broke, his didn't.
I tried my headset on his PC with his cable and that was the only way I could get it to work.
I spoke to Oculus support on live chat, told them all of this, and they sent me a new cable within the week - for free.
Get the box you got the Oculus in, prepare to be on live chat for a little while and they'll send you a new cable.
Since day one of buying this headset in Oct 2020, daily, I get:
1. Screen display flashes/freezes for a blink, then goes black
2. I check Oculus app and it says only: USB disconnect
3. I must first unplug and re-plug the USB into my PC
4. Then, I get a message saying: Display adapter disconnect
5. Un-plug/re-plug the display adapter (straight from Rift S cord into back of PC video card slot, no adapters used)
6. Status goes back to green
7. I re-enter VR
This repeats about every 20-60 minutes every single time I use the headset. (Many times while using Microsoft Flight Sim when I am 20 seconds from landing on the runway)
I have posted and posted and have given up. Oculus is not able to resolve this issue.
Worse yet, every time Oculus updates this, I now do not know whether I should be using the beta version, or not.
This whole thing has been one of the most frustrating experiences I have ever had with any product I have ever bought in my entire 53 years. And I bought the Quest 2 and that sucks trying to get it to work right with MSFS2020. It hurts your head. Oculus screwed up not using the head design from the Rift on the Q2. The Rift headset is one of the most comfortable headsets I have owned (several). The Q2 feels like cheap junk. And the performance I am getting with all three of my flight sims is a major pain to work with, when I do manage to get the Q2 working right.
I'll try a cable. It is about the only thing I havent tried yet. Kinda sucks I have to now spend an additional what, $125 for one??? Thanks, Oculus.
