7-Port USB Hub   
System Contents
Model 1117 7-port USB Hub (with stand)
2.5’ USB cable for connection to a computer
User Manual
CAUTION
 
THIS USB HUB IS RATED TO ALLOW FOR 1.5 AMPS OF CURRENT 
WHEN BUS-POWERED (WITHOUT ANY EXTERNAL POWER ADAPTER). 
BEFORE CONNECTING ANY DEVICES TO THE USB HUB, ENSURE 
THAT THE TOTAL MAXIMUM CURRENT DRAW OF EACH OF THE 
DEVICES ADDED TOGETHER IS LESS THAN THE CURRENT RATING OF 
THE USB HUB AND THE COMPUTER’S POWER SUPPLY. FAILURE TO 
DO SO MAY DAMAGE THE PC, THE USB HUB, AND/OR ANY 
DEVICES CONNECTED TO THE USB HUB.
IF YOU ARE USING A LARGE NUMBER OF DEVICES OR VERY 
POWER-INTENSIVE USB DEVICES, AN EXTERNAL DC POWER 
ADAPTER WITH A RATING OF UP TO 5V/3.5A MAY BE USED TO 
PROVIDE ADDITIONAL CURRENT.
Setup & Operation
1. Connect the square (Type “B”) connector of the 
included USB cable to the USB hub.
2. Connect the flat (Type “A”) connector of the cable to 
one of the computer’s USB ports.
3. The red power LED should light. The USB hub should 
automatically be detected by the computer. Allow the 
computer to completely install the device. It should 
indicate when it has completed.
4. You may now begin connecting devices to the hub 
one at a time. Use the 7 USB ports on the USB hub as 
you would the USB ports on the computer. The 
computer may automatically detect connected devices 
or it may require drivers for certain devices. Refer to the 
instructions that come with those devices for support 
regarding their installation.

Troubleshooting
USB Hub does not work (Power LED not lit):
•  Check the connection between the computer and hub

to the computer
•  If too much power is being consumed by any of the 
devices, you may need to use an external DC power adapter 
to power the USB hub
