The system board suppor ts 6 USB 2.0/1.1 ports. USB 1.1 suppor ts
12Mb/second bandwidth while USB 2.0 supports 480Mb/second
bandwidth providing a marked improvement in device transfer
speeds between your computer and a wide range of simultaneously

ports. Refer to your operating system’s manual or documentation.
Two onboard USB 2.0/1.1 por ts (CN7 - Black) are located at the
ATX double deck por ts of the board.
The system board is also equipped with JUSB1 and JUSB2 for
connecting 4 external USB 2.0/1.1 ports. The USB 2.0/1.1 ports,
which are mounted on a card-edge bracket, will be provided as an
option. If you wish to use the optional USB 2.0/1.1 por ts, install the
card-edge bracket to the system chassis then insert the connector
that is attached to the USB 2.0/1.1 por t cables to JUSB1 or JUSB2.
The USB ports’ cable connector can be inserted only if pin 1 of the
connector is aligned with pin 1 of JUSB1 or JUSB2. Now connect the
interface cable connector of your USB 2.0/1.1 device to the USB
2.0/1.1 port that is on the bracket.
You can enable or disable the USB por ts in the Integrated Peripher-
als submenu (“USB Controller” field) of the BIOS.
