Introduction
Thank you for purchasing an IOGEAR’s MiniHub -durable
USB hubs with many enhanced features. Or MiniHub
products expand your current USB configuration by
increasing the number of available USB ports. There has
never been a more convenient way to expand your USB
capacity. Since many USB devices draw power from the
USB port on your computer, problems can arise when
power-hungry devices (such as scanners, printers, etc.) are
connected to your system. That’s why our MiniHub &
MiniHub Plus come with power adapters for self-powered
operation. This ensures the hub has enough electricity to
power all your connected USB devices. For more technical
information regarding your MiniHub, please see the
Features & Specifications section in this user manual.
System Requirements
Any PC or Macintosh computer with an
available USB port and a USB-compliant
operating system (Windows 95 OSR 2.0,
Windows 98, MacOS 8.1 or later. etc.).

Overview
1) Power LED
This LED lights up when the MiniHub is receiving
power.
2) Downstream Ports
Connect your USB peripherals to these ports.
3) Downstream Port LEDs
These LEDs provide information regarding port status
and overcurrent detection. When a device is
connected to one of the downstream ports, the
associated LED will light up. If an overcurrent
condition is detected, the LED for that port will turn off,
indicating a problem with that device.
4) Root (Upstream) Port
This port connects to your PC or Mac to provide a link
between the peripherals and your computer.
5) Power Jack (G-UH124x & G-UH7144 only)
Connect your MiniHub power adapter here. This hub
operates in self-powered mode to ensure that enough
power is provided to your connected USB devices.

Installation may be done whether your computer is
powered-on or off.
1) Connect the A-B cable (included in this package) to
the Upstream port on the MiniHub, then connect the
other end of the cable to an open USB port on your
PC or additional USB hub.
Note: The MiniHub Lite has a built-in A-B cable. Simply
connect the MiniHub Lite directly to your computer, then
connect your peripherals to the two downstream ports.
2) Connect your USB peripherals to the Downstream
ports on the MiniHub.
Self-Powering the Hub:
Self-Powering is necessary for G-UH124x users and
is optional for G-UH7144 users. If you'd like to run
the hub in self-powered mode, connect the DC
power adapter into the power jack on the MiniHub,
then plug the power adapter into your wall outlet.
