difficulty with the portable ps2 controller Brazil

Good night my friends, sorry for the delay in posting, so I came across another obstacle, I've already tested 2 controls and it didn't work, I measured the voltage and all the control points are at 3.4v so I don't know where I'm going wrong anymore

Hello, friend, if all your wires are connected correctly, the problem is that you do not connect the joystick. If you do not connect the joystick, the direction will keep moving, and the result is that you cannot input other keys.
