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 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 support USB 1.1 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.
