INTRODUCTION
Congratulations and thank you for purchasing the Belkin Hi-Speed USB
2.0 4-Port TetraHub (the Hub). The Hub provides four downstream USB
ports that offer backward-compatible, Plug-and-Play connectivity with all
USB devices, including USB 1.1 (or low- and full-speed) devices, as well
as with USB 2.0 (or high-speed) devices. This includes such peripherals
as scanners, printers, mass-storage devices, and high-resolution cameras.
The Hub is self-powered, which allows the cascading of devices with
additional hubs, so that up to 127 USB devices may be connected to a
single port.
The Hub features multicolor LEDs that indicate the operating speed of
each connected USB device and the speed of the link to the host
computer. For additional information, refer to the “Technical
Specifications” section.
The TetraHub offers several important advantages over traditional USB
2.0 hubs. Most important is its implementation of the new “Quad TT”
architecture. Simply stated, when connected to a USB 2.0 host
controller, each of the TetraHub’s four downstream ports deliver a full
12Mbps of USB bandwidth for low- and full-speed devices while still
providing total support for high-speed devices. This is especially
important when connecting multiple, bandwidth-intensive, full-speed
devices such as USB webcams, speakers, scanners, and external storage
devices.

INTRODUCTION
In contrast, a traditional four-port USB 2.0 hub provides only 12Mbps of
bandwidth for use by low- and full-speed devices, and this bandwidth is
shared by each of the four ports. The TetraHub delivers up to 48Mbps of
bandwidth, 12Mbps for each port!*
In addition to the “Quad TT” feature, the TetraHub also monitors the
speed of each connected device and provides users with a visual
indication of its connected speed. Refer to the “Determining the Speed
of Connected Devices” section of this User Manual for additional
information.
*In cases in which the TetraHub is connected to a USB 1.1 host
controller, the maximum USB 1.1 bandwidth of 12 Mbps is shared across
all four ports.

INSTALLATION
Important Note: Please do not connect any USB devices to the Hub until
instructed to do so in step 4 of this installation
procedure.
1. Plug the AC adapter into a wall outlet or surge suppressor. Plug the
DC connector into the DC power jack found on the rear of the Hub.
Note: The Hub may be used without the power supply with most USB
devices
2. Plug the flat end (USB-A connector) of the provided USB device cable
into the downstream port of your computer or downstream port of
another hub. Plug the square end (USB-B connector) into the USB-B
connector on the back of the Hub.
Important Note: The Hub must be connected to a USB 2.0-compliant host
in order to function in high-speed mode (480Mbps data
rate). If the Hub is connected to a USB 1.1-compliant
host, it will operate only in low-speed or full-speed mode
(1.5Mbps/12Mbps).
3. Windows will now detect your Hub and install the required driver
support. (The Windows “Install New Hardware Wizard” may prompt
you to provide your Windows Installation CD to complete the driver
installation process).

INSTALLATION
Important Note: High-speed hub drivers are included with most USB 2.0
PCI upgrade cards, and are preinstalled along with the
PCI card drivers. If you purchased an upgrade card prior
to the release of high-speed hub support, please check
with your PCI card vendor for an updated USB 2.0 driver.
The Belkin USB 2.0 driver supports all competitive cards
based on the NEC host controller with the exception of
Adaptec. The most recent Belkin driver is available at
www.belkin.com.
