Installing Drivers  
Installing Drivers  
USB 2.0 driver software with hub support must be installed on  
your computer for the XHub for Notebooks to operate at USB 2.0  
speeds. If you are using an Adaptec USB 2.0 controller, install the  
USB 2.0 drivers provided on the XHub for Notebooks CD.  
Note: The drivers provided on the XHub for Notebooks CD  
will not work with non-Adaptec USB 2.0 controllers. Refer to  
your controller’s manufacturer for driver information.  
Follow the instructions for your Operating System (OS) to install  
the USB 2.0 drivers:  
For Windows 2000, Windows Me, or Windows 98SE, see below.  
For Windows XP, see page 6.  
For Macintosh, see page 7.  
Note: Adaptec strongly recommends that you always use the  
most recent drivers to maximize your XHub’s performance.  
Regularly check the Adaptec website at www.adaptec.com for  
the most up-to-date USB 2.0 drivers.  
Windows 2000/Me/98SE  
Turn on your computer and connect your AUH-4100 (see Plugging  
in Your XHub on page 4 for instructions). Insert the XHub for  
Notebooks CD into your CD-ROM drive. Windows loads the  
driver automatically.

Installing Drivers  
Macintosh Operating Systems  
Because there are currently no USB 2.0 drivers for the MacIntosh  
OS, you don’t need a special driver to use the XHub for Notebooks  
with your Macintosh computer. (Your XHub for Notebooks will  
operate at USB 1.1 speeds.)  
Note: The drivers included on your XHub for Notebooks CD  
will not work on your Macintosh computer.  
To verify that the XHub for Notebooks is recognized by your  
system:  
1
Turn on your computer and connect your AUH-4100 (see  
Plugging in Your XHub on page 4 for instructions).

XHub for Notebooks User’s Guide  
Installing USBControl  
USBControl is a software utility that helps you easily manage your  
USB peripherals. Using USBControl, you can find information on  
device performance and status, and get detailed device  
information and troubleshooting help.  
To install USBControl, insert the XHub for Notebooks CD into your  
CD-ROM and follow the on-screen instructions.  
Note: USBControl runs with Adaptec USB 2.0 controllers, and  
on Windows OSs only.  
Plugging in Your Devices  
Follow the picture below to connect your USB 1.1 and 2.0 devices  
to your XHub for Notebooks. You can plug devices into any of the  
four USB ports.

Note: USB 1.1 devices won’t operate at USB 2.0 speeds, even if  
they’re connected to USB 2.0 hubs or controllers. Your XHub  
must be connected to a USB 2.0 port for it and your USB 2.0  
devices to operate at USB 2.0 speeds. (See USB 1.1 vs USB 2.0  
on page 11 for more information, and Macintosh Operating  
Systems on page 7 for special limitations for Macintosh users.)

Understanding the LEDs  
Understanding the LEDs  
Your XHub for Notebooks has 6 colored LEDs to help you monitor  
the status of your XHub and USB devices. Refer to the figure below  
for the location of each LED.

The red Power LED indicates that the XHub is connected to a  
power source and that the power is on.  
The green USB Uplink LED indicates that the XHub is properly  
connected to a USB port on your computer, and that a USB 2.0  
driver (version 3.0 or later) is installed. (See Installing Drivers on  
page 5 for more information.)  
The four USB Device LEDs (numbered 1 through 4) indicate the  
status of the four USB ports on your XHub (numbered 1  
through 4). When a Device LED is illuminated, a USB device is  
connected to the corresponding USB port.

XHub for Notebooks User’s Guide  
If you want to add more USB 2.0 ports to your system, Adaptec  
XHubs can be daisy-chained (linked in series). You can connect up  
to five XHub for Notebooks hubs. (This is a USB limitation.)  
To daisy-chain XHubs:  
1

Connect a power adapter to each XHub. (See Plugging in Your  
XHub on page 4.)  
Plug the first XHub’s USB cable into the USB port on your  
computer.  
Plug the next XHub’s USB cable into a USB port on the first  
XHub. You can use any available USB port.

About USB  
About USB  
USB stands for Universal Serial Bus. It is the interface between  
your computer and the USB devices you plug into it. Your  
computer communicates with USB devices through the USB  
interface.  
Some USB features are particularly important to desktop computer  
users:  
USB is one-size-fits-all—any USB device can be plugged into  
any USB port using the appropriate USB cable.  
USB devices feature plug-and-play installation—you don't have  
to open your computer or add special hardware to install a new  
USB device. Once you plug your USB device into your  
computer (or hub) and turn it on, you can start using it right  
away.  
You can hot-swap USB devices. You can easily unplug your  
digital camera to take away with you, or plug in your joystick  
during your lunch break.  
You can have many USB devices connected to your computer at  
once. Most newer computers come with 2 USB ports. USB hubs  
can provide additional ports.  
USB 1.1 vs USB 2.0  
USB 2.0 transfers data at 480 Megabits per second. USB 1.1  
transfers data at 12 Megabits per second—that makes USB 2.0 up to  
40 times faster than USB 1.1.  
USB 1.1 devices cannot operate at USB 2.0 speeds even when  
connected to a USB 2.0 hub or adapter.  
11  
 
   
XHub for Notebooks User’s Guide  
Maximizing XHub Performance  
For your XHub for Notebooks to operate at optimum speed, it  
must be connected to a USB 2.0 port, and USB 2.0 driver software  
with hub support must be installed on your computer.  
Note: Macintosh users—There are currently no USB 2.0 drivers  
for the Macintosh OS, and USB 2.0 PCI cards will not work on  
Macintosh systems. Your XHub for Notebooks will operate at  
USB 1.1 speeds.  
If your computer does not have a built-in USB 2.0 port, we  
recommend connecting the XHub for Notebooks to an Adaptec  
USB 2.0 card for the highest-quality USB 2.0 connection. (For  
information on USB 2.0 adapters, go to the Adaptec website at  
USB 2.0 drivers with hub support can be found on the XHub for  
Notebooks CD included in your kit. See Installing Drivers on page 5  
for more information.

Note: The XHub for Notebooks can operate without a power  
adapter if it is connected to a bus-powered USB device, such as  
a mouse, keyboard, or zip drive. However, if the total power  
consumption of the USB devices connected to the XHub  
exceeds 490 mA, a power adapter must be used. Use Adaptec  
USBControl to determine the power consumption of your  
devices. Refer to USBControl online help for more information.
