Using the USB (Universal Serial Bus) HUB Featuers
Universal Serial Bus (USB) is an innovation that conveniently connects
different devices to your computer. USB enables you to have the flexibility to
connect your mouse, keyboard, and other devides to the monitor instead of the
computer. The Speaker/USB HUB Option provides a 4 port USB HUB that will
enabel you to connect a chain of up to 120 devices on a single USB connection.
You can "hot-plug" USB devices, that is, you can attach the devices while the
computer is on. You can also disconnect USB devices while maintaining "Plug
and Play" auto detection and configuration. This monitor comes with an
intergrated BUS-power USB hub that can have up to four other USB devices
attached to it. The Speaker/USB HUB Option has an intergrated BUS-powered
HUB that meets the USB 2.0 Specification for Full Speed Devides, allowing up
to 4 low power (<100 mA each) USB devices to be attached.
