Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Couch Co-op on PC, how does player 2 join game?

Trying to start a new game (1st ever play through of game) on PC using 2 Xbox 360 controllers. I see the in game settings only allow for choosing a Xbox One controller, but it seems selecting that allows the 360 controller to work just fine as well for player 1. But the second controller does nothing, no buttons function besides turning the controller itself on, so 2nd player can't join game. Maybe worth noting that both controllers show up as Player 1 by the little lights in the top middle of controller... Do I need to change that? If so, how? Any help appreciated. Thanks.

You hit the small 'Start' button on the second controller?
Try unplugging the second controller and plugging it back in. That should fix them both identifying as the first controller.
