For some reason, when I configure it to connect from SFV it works for 15 seconds or so and then it would stop working. I would reconnect it from the menu and it would work for a short period of time before stopping again.
Is there something wrong with my stick or is the game just buggy?
I have that stick as well. It works fine on my first PS4, but it times out after 30 seconds or so on the Star Wars limited edition PS4 that I recently purchased. I have contacted Sony and they told me that the newer PS4s have different components that affect the backward compatibility with this stick.
