Universal Serial Bus (USB) Interface

The main board provides a double-stacked USB port and the peripheral board provides two single
USB port connectors. See Table 36. These built-in USB ports permit the direct connection of four
USB peripherals without an external hub. If more devices are required, an external hub can be
connected to either of the built-in ports.
