The Star64 board has no GPIOs to indicate USB overcurrent, however the USB controller would stop to work if the overcurrent_n signal it gets is low (which means overcurrent situations happening because of the _n). Use the pin controller to force the overcurrent_n signal to be high in order to ensure stable behavior of the USB controller.
