USB Device Connection
USB hubs can be connected to a USB port on the notebook or on
an optional docking device, 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 port on the notebook or to a port on a
powered hub.
Operating System and Software
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
installed in the notebook.
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.
