Universal Serial Bus (USB) Ports
There are two USB 3.0 ports (USB 4/5) located on the I/O back panel. The motherboard also
has a front access USB 3.0 header that supports two USB connections (USB 6/7). A USB
Type A header, USB 8, provides also USB 3.0 support. The onboard headers can be used
to provide front side USB access with a cable (not included).
