Using a USB device
Universal Serial Bus (USB) is a hardware interface that can
be used to connect an optional external device, such as a USB
keyboard, mouse, drive, printer, scanner, or hub, to the computer
or to an optional docking device. A hub provides additional USB
ports for the system and can be connected to the computer or to
another hub.
The computer has 3 standard USB ports that support USB 2.0 and
USB 1.1 devices. An optional docking device provides additional
USB ports that can be used with the computer.
