As you can see this random website (just googled "controller inputs" and picked the first result. The website is hardwaretester.com/gamepad fyi) recognizes my joysticks, but DoD doesn't recognize the right one and the left one are the directional keys when rebinding inputs, while the keys themselves just don't work.
Halp.
Apparently it's binding mouse inputs(Mouse Click 1 to be precise) when I'm pressing the "A" button on the controller.
PS: I'm not using an official 360 controller, it's a random logitech one from a few too many years ago.
