Installing the Motherboard

F_USB1: Front Panel USB header

The motherboard has four USB ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB ports at the front of the case. If you
have this kind of case, use auxiliary USB connector to connect the front-mounted
ports to the motherboard.

Please make sure that the USB cable has the same pin assignment as
indicated above. A different pin assignment may cause damage or system
hang-up.
