Unreal Engine 4.23 Released!

Yes, I had this problem also with my Rift. I ended up discovering after much troubleshooting that the USB plug on the Rift itself was causing a problem with my USB port (which is a known problem). Eventually switching it to a different port + disabling power management in the USB devices (Device manager) took care of the problem on my system (trying different ports then rebooting after each and so on). Not sure the same will help with the Rift S though.
