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
