Universal Serial Bus (USB) Interface
The baseboard provides two stacked USB ports (port 0 on top, port 1 on bottom). The
built-in USB ports permit the direct connection of two USB peripherals without an
external hub. If more devices are required, an external hub can be connected to either of
the built-in ports. Table A-6 shows the cable pinout assignments for the USB connector.
