Universal Serial Bus (USB) Ports
There are four USB 3.0 ports (USB0/1/2/3) and one USB 3.1 ports (USB4) located on the
I/O back panel. The motherboard also has a front-accessible USB 3.0 header that provides
two USB 3.0 connections (USB5/6) and a front-accessible USB 3.2 Gen 2x1 Type C header
(USB7). The onboard headers can be used to provide front side USB access with a cable
