USB hubs can be connected to a USB connector on the notebook
or on an optional Port Replicator 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.
A USB device functions in the same way as a comparable
non-USB device, with one exception. By default, USB devices do
not function unless an operating system that supports USB is
loaded.
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.
