Question Msi z370 krait usb ports not working

[koirakala]

So I bought this motherboard "used", the seller got it from the factory with one usb port broken and got it fixed. He hadnt tried if it worked. I paired the board with an i5 9600k (I was told the bios would be compatible) and now there is 1 single usb port in the whole system that actually works. All the others give some sort of trigger and the devices I plug in light up for a second and go dark again. Charcing a phone works normally, however the phone does not detect what its plugged in. What could cause this?
