DETERMINING THE SPEED OF CONNECTED

DEVICES

1.The USB 2.0 specification includes three separate modes of data transmission. These are defined as low-speed (1.5Mbps), full-speed (12Mbps), and high-speed (480Mbps). The Belkin TetraHub is the only USB hub on the market today that provides a visual indication of a connected device’s speed. This is accomplished using proprietary speed indication circuitry. Each downstream port on the Hub has a corresponding LED that changes color according to the speed of the connected device as noted below.

Connection Speed	LED color
Low	Green
Full	Red
High	Amber

2.In addition, the upstream port has a corresponding LED that indicates the speed of the computer’s USB host controller as noted below.

Host Controller Speed	LED color
Full	Red
High	Amber

Note: The Hub itself will always connect to the host as either a full- or high-speed device, never as a low-speed device.
