3.

The addition of this new hardware will be “sensed” by Windows and the “Add New Hardware Wizard” will auto-
matically be launched, anticipating the installation of a device driver for the new hardware. Insert the W

IN

D

AQ

 

Resource CD-ROM into your CD-ROM drive. The root directory of the CD contains all USB drivers.

4.

From the initial “Add New Hardware Wizard” screen click Next to get started, then choose the “search for best 
driver option (recommended)” and click Next.

5.

Specify the CD-ROM drive that contains the W

AQ

 Resource CD-ROM as the search location and click 

Next

.

6.

Follow the on-screen prompts. Depending on how Windows was originally installed on your computer, you may 
need additional files from your Windows distribution CD-ROM to complete the driver installation. When you 
see the following dialog box, Windows has located the necessary device driver and is ready to install the required 
files. Click
