2. F_USB1~2: Front Panel USB 2.0 headers
The motherboard has two USB 2.0 headers supporting four USB 2.0 ports. Addition-
ally, some computer cases have USB 2.0 ports at the front of the case. If you have this
kind of case, use auxiliary USB 2.0 connector to connect the front-mounted ports to
the motherboard.
Please make sure that the USB cable has the same pin assignment as indi-
cated above. A different pin assignment may cause damage or system hang-
up.
