Universal Serial Bus (USB) Interface

The main board provides a double-stacked USB port at the rear panel and one vertical USB port
located in the middle of the main board. The front panel I/O board provides three stacked USB port
connectors via a USB hub controller. These built-in USB ports permit the direct connection of six
USB peripherals without an external hub. If more devices are required, an external hub can be
connected to any of the built-in ports.
The pinout for the dual USB connector is listed in Table 16. The pinout for the triple USB
connector on the front panel I/O board is listed in Section 8.
