USB ports are dead

Hi guys. I have a RaspberryPi 4B 4GB (newer version) that had 9V instead of 5V put through the USB-C power input according to owner.

Surprisingly it boots and works, but ethernet and USB ports are dead. I replaced the BCM54213PE and VL805 chips I took from a donor board - ethernet works fine now, but no luck with USB.

I also replaced the crystals next to both of those chips - didn't help either.

Any ideas what else I should check?
