Connecting a USB Device
USB (Universal Serial Bus) is a hardware interface that can be
used to connect external devices such as a USB keyboard, mouse,
drive, printer, scanner, or hub to the notebook.
A hub is a connecting device that can be either powered or
unpowered. USB hubs can be connected to a USB connector on
the notebook or to other USB devices. Hubs support varying
numbers of USB devices and are used to increase the number of
USB devices in the system.
■ Powered hubs must be connected to external power.
■ Unpowered hubs must be connected either to a USB
connector on the notebook or to a port on a powered hub.
The USB connectors on the notebook support USB 2.0- and
1.1-compliant devices.
By default, USB devices function only while the operating
system is loaded. To use a USB keyboard or hub connected to a
USB connector on the notebook during startup (before Windows
loads) or in a non-Windows application or utility, enable USB
legacy support in the Setup utility. For more information about
using the Setup utility, see the “Using the Setup Utility” section
in Chapter 9.
