Most common case is the burn fuses of the USB port.

A) Check the fuses – if available

B) You can check the power rails and it should be 5V – if you get >4.0V check the main PMU (Power management unit)

C) 3rd Gen Intel core CPU works with PCH (Platform Controller Hub), the PCH is the responsible chip for USB functioning
