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.
Some USB devices may require additional support software, which is usually included with the device. For
more information about device-specic software, see the manufacturer's instructions. These instructions
may be provided with the software, on disc, or on the manufacturer’s website.
The computer has at least 1 USB port that supports USB 1.0, 1.1, 2.0, or 3.0 devices. Your computer may also
have a USB charging port that provides power to an external device. An optional docking device or USB hub
provides additional USB ports that can be used with the computer.
