I found a way to get my PS controller working for LE and wanted to share if anyone is also running into the same issues. It seems like Steam’s own controller support can interfere with LE.
For Non-Game Controller Layout I chose official layout.
Go in to Steam’s settings and pull up the controllers. Turn off steam input for Xbox controller. Turn on Steam Input for generic controllers and PS controllers.
Still can’t map any buttons but seems to allow the PS controller to work in game.
