I’ve seen several discussions about it but thought it might be nice to have a sort of top level discussion about it, gather all the data and get everyone’s input.

Symptom: USB-C drives plugged directly into the Steam Deck OLED will not show up/mount. It is as if you didn’t plug anything in at all. Plug the same drive into the LCD Deck? Pops right up.

The Deck will charge from the port - and bios will see a compatible boot device and you can boot to recovery.

If you plug pretty much any hub into the Deck? Any USB drives connected to the hub WILL show up.

Thoughts, fixes, more data - all appreciated. Thanks!
