[Help] Gamepad doesn't work

Hello. I’m using a 8BitDo SN30 pro+ controller plugged in via USB. I tested it in Steam Big Picture Mode so I know that it is working, but when I open Unreal, it doesn’t register the controller at all.
I’ve tried it with engine input bindings, getting the gamepad values in blueprints; nothing is registering at all. I’ve tried both in editor and packaging the project, and nothing.
Any ideas?

Make a basic widget and put a InputKeySelector in it.

When you run it and click on the box, then you can press a gamepad key. If nothing registers then, UE is really not seeing it…
