I have a strange issue with this one. None of the usb ports works properly. If a usb mouse is connected, left and right clicks works but cursor movement does not. None of the other usb devices works. I have checked all usb input filters,no issues there. I have changed FCH with new one but issue remains. motherboard: X550ZE rev 2.0 KBC: ITE 8528E AMD a10 cpu with discreete gpu Any experience with this? |

I`ve got this sorted... Shorted gate to source at q9102 transistor. Because of this i was getting 5,7v (resistor divided gate from 12v) on USB V+, which drops down to 2,5v as soon as i plug usb device. Did not notice before. Replaced transistor, all good. |
