USB Support

USB is a new serial bus design that is capable of cascading low
and medium-speed peripherals (less than 12 Mbps) such as a
keyboard, mouse, joystick, scanner, printer and modem/ISDN.
With USB, complex cable connections at the back panel of
your PC can be eliminated.

The board comes with two USB ports. See “Board Layout” on
page 26 for the location of the ports.
