I'm trying to play the game with the USB PlayStation Classic controller and it isn't working. The PC is reading the controller and it works with other programs. I've gotten a bluetooth Xbox controller to work with the game, but I want to use the PlayStation Classic controller for obvious reasons. Has anyone gotten it to work?

Some gamepads don’t work initially. What you can do is add the game as a non-steam game to Steam, and then set up controller configuration following the guide below:

Yeah, this controller makes Steam shit itself. That's not going to work.

DS4Windows works if you have a ds4 controller.

I have tried mapping out inputs via steam, but it essentially made Steam shit itself, like you said. What's more annoying is that if i play Resident Evil 0 (the remake) I have full PSC controller support, where as with this game It won't work. Super annoying.
