Wha's happening, since i updated my B650E-E bios lastly (march) i got Win (11 only now) errors memory couldn't be read, also appeared a few times on SteamDeck after bios update !!
It's when i turn OFF pc, only, and only if a (USB) gamepad is connected during power down (or mouse receiver if i use my wireless mouse btw), and on Deck even if nothing is wired to any USB (the bios update says, now default USB set to xhci instead drd, that i tried to switch back but error poped up too, sometimes anyway, it's razrely on Deck, always on my desktop if pad or wireless USB's plugged!..
Keyboard mouse don't happen to have the error shown by Win, never (happyly)
