Vewlix Controls not working with Brook UFB + Arthrimus Vewlix Console I/O + PS4 Pro

I just placed a PS4 Pro inside the Vewlix. For controls, I'm using an @Arthrimus Vewlix Console I/O with two Brook Universal Fighting Boards. The Brook UFBs are connected to the PS4 Pro directly using USB 2.0 cables. The Sanwa buttons and Sanwa sticks are connected to a complete G Harness by @Lemony Vengeance.

I just wanted to see if I'm missing something here. I did a quick test to make sure the sticks and buttons worked before finishing up the cable management. This is when I found out they're not responding. Any thoughts?

Your cabling looks correct.
Remember you have to press the PS button from the Brook UFB after the PS4 has been switched on to register the controller.
Unless your PS button is wired (which does not seem to be the case here), you can emulate it by pressing 2+3+Start simultaneously.

That was it! Appreciate this, @VxD!

I have a harness ready for the PS button. Just haven't installed it yet.
