Do the USB ports show in Device Manager?

If so that indicates that the USB controller (maybe it is integrated in the motherboard chipset and is not an individual USB controller) is working, up to a point anyway i.e. BIOS to USB controller is OK but not USB controller to USB port.

You will have to trace the 5V USB power supply and the data lines back from the USB ports using the schematic and check where they end up.
