2.23USB connectors (CN20, CN28)

The PCM-9575 board provides up to four USB (Universal Serial Bus) ports, with USB3 and USB4 optional. This gives complete Plug and Play, and hot attach/detach for up to 127 external devices. The USB interfaces comply with USB specification Rev. 1.1, and are fuse protected.

The USB interface is accessed through two 5 x 2-pin flat-cable connec- tors, CN20 (USB1, 2); and CN28 (USB3, 4). You will need an adapter cable if you use a standard USB connector. The adapter cable has a 5 x 2- pin connector on one end and a USB connector on the other.

The USB interfaces can be disabled in the system BIOS setup.
