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:

1Turn on your computer and connect your AUH-4100 (see Plugging in Your XHub on page 4 for instructions).

2Open the Apple System Profiler and check that USB2.0 Hub Controller appears in Devices and Volumes under USB, as shown in the example below.

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.)

■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

Daisy-Chaining XHubs

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:

1Connect a power adapter to each XHub. (See Plugging in Your XHub on page 4.)

2Plug the first XHub’s USB cable into the USB port on your computer.

3Plug the next XHub’s USB cable into a USB port on the first XHub. You can use any available USB port.

First XHub in chain: cable to USB port on computer

4Repeat until all your XHubs are daisy-chained together.

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 www.adaptec.com.)

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.
