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.
