About USB  
USB, which is short for Universal Serial Bus, is a  
technology designed to make connecting devices  
to computers easier. Originally developed in 1996  
by a group of computer industry leaders that  
included Compaq, Digital, IBM, Intel, Microsoft,  
NEC, and Northern Telecom, USB is quickly  
becoming the first choice for users who want to  
add peripherals to their computers.  
USB is unique because it is plug-and-play, which  
allows a computer to instantly recognize when a  
device like a keyboard, mouse, or scanner has  
been connected to it. Once the device has been  
recognized, its ready to go -- no special setup is  
required. Similarly, USB supports hot-swapping --  
the insertion or removal of devices while the com-  
puter is turned on. You can swap one device for  
another without having to power down your sys-  
tem or install any special software -- it really is  
that easy.  
Another unique USB feature is its ability to allow  
multiple devices to be connected to a computers  
single USB port. The USB 4-Port Hub, for exam-  
ple, splits a computers USB port into four USB  
ports. All four ports can operate simultaneously  
and independent of each other, allowing easy

should plug the AC adapter into your hub.  
Hardware S e tup  
If you decide to use the AC adapter, plug it into  
the hubs AC power adapter receptacle located on  
the rear of the hub now.  
Before installing the hub, make sure you have  
received all of the following items. If any of the  
items are damaged or missing, contact your ven-  
dor for replacements:  
Step 2  
• USB 4-Port Hub  
• AC Power Adapter  
• 6’ USB Cable  
• Plug your computer into the hub.  
The USB 4-Port Hub came with a USB cable. One  
end of the cable has a rectangular plug, which is  
called an A-type connector. The other end of the  
cable has a square shaped plug, or B-type connec-  
tor.  
After unpacking the hub, follow the steps below to  
complete the installation.  
Step 1  
Insert the cables square B-type plug into the hubs  
Root Port, which is located on the rear of the hub.  
• Plug in the AC power adapter (optional).  
The USB 4-Port Hub can run with or without its  
AC power adapter. If you decide not to use the  
adapter, the hub will draw its power supply from  
your computers USB port.  
If you have a notebook computer, or if you have  
lots of devices connected to your computer, you  
might want to use the AC power supply -- it can  
help boost signal strength between a PC and its  
devices, and if you have a notebook, it will help  
preserve your computers battery life.  
Insert the other end of the cable (the A-type plug)  
into your computers USB port. The computer is  
now connected to the hub.  
Some USB devices require more power than the  
hub can supply in self-powered mode. If you plug  
a device into your hub and it doesn’t work proper-  
ly, it may need more power. In this case, you

Step 3  
LED Indicators  
• Plug your USB device(s) into the hub.  
While you are using your USB 4-Port Hub, one of  
the two power LEDs will be lit. Depending on  
whether or not you have chosen to use your hubs  
AC power adapter, you will see one of the follow-  
ing light up.  
The front of the USB hub has four rectangular A-  
type ports where you can plug in USB devices. To  
plug in a USB mouse, keyboard, or other device,  
simply plug its A-type cable into any of the hubs  
four A-type ports. The installation is complete!  
Bus Powered Indicates that the USB Hub is in  
operation and is drawing power  
from your PC.  
Self Powered Indicates that the USB Hubs  
AC power adapter is connected  
and is feeding power to the Hub  
and all devices connected to it.  
If the self powered LED is ON,  
the hub is not drawing power  
from your PC.  
To PC  
Using the Hub with USB Devices  
Using the USB 4-Port Hub with a USB device is  
easy -- after plugging in the device, just turn it on.  
Your Windows 95 (revision OSR2 and above),  
Windows 98, or MacOS computer should auto-  
matically detect it. USB technology specifically  
allows devices to be inserted or removed while  
your PCs power is on -- its true plug-and-play!  
There are also 4 port-specific LEDs on the hub.  
Each LED will light up if the port below it is  
active and has a device attached to it.  
Note: Your operating system must have USB sup-  
port in order for you to utilize the USB 4-Port  
Hub. For instance, some earlier versions of  
Windows 95 do not support USB. If you are not  
sure whether or not USB is supported by your  
operating system, consult the documentation that  
came with the operating system.

Troubleshooting  
S pe cifications  
1. I plugged a device or other hub into my hub  
and it doesn’t work.  
Standard  
OHCI, UHIC, and USB  
Standard v1.0  
First, verify that all of your cabling is connected  
properly. See page 6 for help. Next, verify that  
you are using an operating system that supports  
USB. Some versions of Windows 95, Windows  
NT and a number of Unix-based operating sys-  
tems do not support USB.  
Ports  
1 Root Port; 4 Device Ports  
Speed  
12Mbps (High Speed)  
1.5Mbps (Low Speed)  
Depending on Device  
Requirements  
Some devices require more power than the hub  
can supply in bus-powered mode. If a device does-  
n’t work and you hub is in bus-powered mode,  
plug in the AC adapter.  
Data Modes  
Isochronous and Asynchronous  
Max Devices 127 (when multiple hubs are  
daisy-chained together)  
If you are connecting a device into your hub via a  
serial-to-USB or parallel-to-USB converter, make  
sure that the device does not require any more  
than 500mA of power. 500mA is the maximum  
amount of power that a USB port can supply. Any  
device that needs more than 500mA of power can-  
not be accessed through a USB port.
