I have had my rift s for a few months now and am having the same problem. I had a friend come over and plug his occulus rift s in and it works fine. Every time I shutdown my computer oculus drivers are gone when I restart. I have to plug in the headset wait awhile and try to reinstall with the device manager. When I plugged in my friends it just worked. I do eventually get it to show up but I have to play this little game when I start my computer. I have done all the troubleshooting there is, but I was wondering if I missed something. Maybe someone can help.
