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. Devices can be connected
to the system.
Some USB devices may require additional support software, which is usually included with the
device. For more information about device-specific software, refer to the manufacturer's instructions.
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.
