TARGUS D E S KTOP USB

2.0 7

-PORT HUB WITH

AUDIO PASS-THROUGH

Introduction

Congratulations on your purchase of the Targus Desktop
USB 2.0 7-Port Hub with Audio Pass-Through. This
desktop hub allows you to expand your desktop by
adding 7 additional USB ports with over-current
protection, and audio pass-through ports for easy
connection of headphones/speakers and a microphone.

The desktop USB 2.0 7-port hub also offers three unique
features:

1 High Power technology - provides twice the USB

specification for devices that require more power than
normal USB ports provide

2 Targus Always On technology - provides power to the

USB ports even when when the computer is shut­down, disconnected, or in hibernation/ stand-by mode.
This allows USB devices that charge via the USB port
to keep charging under any circumstance.

3 Targus Easy Access Ports - USB ports are spaced

wider apart to accomodate larger USB adapters.

Connecting New Devices

To avoid possible damage when connecting a new
device, do not force the cable connector into the port on
the USB hub. If the cable connector does not attach
smoothly, turn the connector over and try attaching it
again.

Connecting a USB Device

To connect a USB device, plug it into a USB port and
follow the additional instructions provided with the device
or on your computer screen.

All seven USB ports meet USB High-speed
requirements, of which two of them are High Power USB
ports, with unique features. See “Targus Always On” on
page 11 for more details, and “Using USB Devices That
Require More Power” on page 11

The standard USB ports, which are located next to the
microphone port and the High Power USB port at the top
of the hub, are high-speed ports that provide standard
500mA of power.

Global Suspend Mode

When your computer is in suspend mode, the USB 2.0 7­port hub also enters suspend mode to avoid power
consumption. When your computer wakes up, so does
the hub automatically.

Targus A l ways On

The two USB ports that provide up to 1Amp of power will
continue providing power even when the laptop is
powered down or disconnected from the USB 2.0 7-port
hub. This allows you to charge any USB device you may
have connected.

Using USB Devices That
Require More Power

Some devices, which use large amounts of power, such
as printers and optical drives, should be plugged into the
USB High Power Ports. These ports will provide up to
1000mA of power - double the power of a standard USB
ports, and are identified by the lightning bolt symbol.

Product Limitations

Some devices may halt temporarily when a high data
transfer is occurring. For example, your mouse may

11

Targus Desktop USB 2.0 7-Port Hub with Audio Pass-Through

respond slowly while a graphic print job is printing or
while you are experiencing heavy network traffic.

We recommend the following guidelines:

• Do not transfer data to or from multiple high-speed
devices, such as a digital camera or scanner, at the
same time.

• If speed degradation does occur, close other programs
that use a USB device to improve device performance.

Troubles h o o t i n g

Device Not Working

• Make sure that the device is fully inserted into the
correct port on the hub.

• Plug the device into a different port. If it still doesn’t
work, test the device by connecting it directly to your
computer.

• Verify that you ran the Setup or Install program for the
device.

• Make sure that the device appears in Device Manager.
For more information refer to “Verifying Devices are
Installed” on page 13.

• Disconnect all devices from the hub and reconnect
them, one at a time. Check that each device works
before plugging in the next one.

• Each USB port is equipped with over-current
protection. Should a USB device draw more current
than the USB port can supply, the port will shut down.

12

Targus Desktop USB 2.0 7-Port Hub with Audio Pass-Through

To re-enable the port, unplug the device and go to
Device Manager or to the message in the system tray
and choose the Reset option. You can then plug the
device back into the USB port. If a shut down reoccurs,
check the power requirements of the device.

Verifying Devices are Installed

You can view the devices installed on the USB 2.0 7-port
hub from the Device Manager window in System
Properties.

Right-click My Computer, Properties, then click the
Hardware tab, and then the Device Manager button.
