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 or optional HP
Notebook Expansion Base.
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 can support several
USB devices.
■ 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
earlier devices.
Some USB devices may require additional support software,
which is usually included with the device. For more information
and software installation instructions, refer to the documentation
included with the device.
