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
integrated BUS-power USB HUB that can have up to four other USB devices attached to it. The Speaker/USB HUB Option has
an integrated 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.
