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.
THE TWO USB PORTS WITH THE LIGHTING BOLT SYMBOL ARE ALSO HIGH-SPEED
PORTS THAT PROVIDE UP TO 1AMP OF POWER EACH. THEY CAN BE USED TO
POWER USB DEVICES SUCH AS HARD DRIVES, PRINTERS, AND EXTERNAL OPTICAL
DEVICES THAT DRAW MORE POWER THAN ASTANDARD USB PORT SUPPLIES.

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

12
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.
Troubleshooting
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.

13
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.
