Connecting a USB Device

USB (Universal Serial Bus) is a hardware interface that can be
used to connect an external device such as a USB keyboard,
mouse, drive, printer, scanner, or hub to the notebook or an
optional Expansion Base.
A hub is a connecting device that can be either powered or
unpowered. USB hubs can be connected to a USB port on the
notebook or to other USB hubs. 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.
The 3 USB ports (select models only) on the notebook support
USB 2.0-compliant, USB 1.1-compliant, and USB 1.0-compliant
devices.
