If I remember this correctly, with the original CV1 headset, the LED colour was:
Orange in standby
White when being used (I could be wrong, it's been a long time since I used my CV1).
No colour change to indicate a problem.
With the Rift-S that changed to:
White when the headset is in standby and there's no problems.
Orange if plugged in but there's a problem e.g. Oculus service isn't running.
LED off when in use.
