The USB_OTG features Low Loss Power Distribution Switch SY6280 which protects the board in
case the devices you have plugged to the USB_OTG attempt to draw more current than 523mA
combined. The maximum current available on the 5V USB_OTG is exactly 523mA. The SY6280
controlling the USB_OTG is enabled by USB0-DRV (processor pin H1).
