USB Device Connection

USB hubs can be connected to a USB connector 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 connector on the notebook or to a port on a
powered hub.
