Same Problem here i tried everything the oculus support recommended but it still happens 😧
but it's really strange i was searching about this problem on google and i found many people with the same problem and i think it is a little odd that oculus still didn't fixed this problem 😞
i mean i have this problem with my Rift S since over 2 years 😧
Where are some tips that helped me
Also using use Oculus Tray Tool this solves a lot of issues for you or makes it possible to switch between energie modes...
Also try other USB ports or check your manual and use the fastest one, I for example have some usb 3.0 and two usb 3.1 ports on my mainboard
