Ps4 12xx too many usb devices connexted

Postby liquidzorch » Wed May 30, 2018 5:48 pm

Hello. I got in a ps4, model 12xx, sac001, that says too many usb devices are connected when nothing is connected. The owner factory reset it, and noe can't get past the welcome screen since the controller can't be connected through USB. In this model it seems the USB is controlled by the SB. Should I try and replace the SB? Or does anyone know of another voltage controller or something? The ports have no voltage. The mosfets do receive 5v, but do not get the signal to output 5v to the ports.

I removed southbridge chip and replaced with same model chip. There is no gl chip like in previous model ps4. Southbridge controls usb.
