Hmm I will see if I can test a ps4 controller soon. Are you on Windows, Linux or Mac?
I know for sure that ps3 and Xbox controllers work. Most any gamepad should work as long as the OS you are using recognizes it and has some kind of driver for it.
I am on windows, and I already have a driver for it, I use it all the time so I don't know why it didn't work even though it's connected.
