Perhaps you're missing the logic/flow to update the power state change

debug without more info.
That may well be what's happening - I believe the driver does indeed
delegate to xhci when in host mode.
What information can we get to you that would help get to the bottom of
this?
Did you seek help from the vendor?
We have/are but we haven't arrived at a fix there yet either.
I'll check both Steam Deck models (LCD and OLED) to see if both can be
quirked in the same way and provide then a simple patch doing that for
review, makes sense?
I assume you ruled out problems from bad cable or faulty laptop/device?
We've had multiple people confirm this behaviour with different power
supplies / cables / devices / kernel versions, so we're sure this is a
"real thing".
