DS4 stopped working

Hello, my DS4 controller stopped working a few days ago and before it just stopped turning on it wouldn't take a charge anymore and also said when connecting to ps4 "too many usb devices connected" regardless of putting it in pairing mode or reseting with the tiny button, so I replaced the usb port and still didn't work, replaced the battery it still didn't work, I replaced the cable connecting the board to the usb port and yet again it still doesn't work, so I repeated pairing mode and reset but its still not turning on
