4.1 INSTALLING VIA THE FOUND NEW HARDWARE WIZARD

To install CDM drivers for an FTDI device under Windows XP, please follow the

instructions below:

 If a device of the same type has been installed on your machine before and the

drivers that are about to be installed are different from those installed already,

the original drivers need to be uninstalled. Please refer to the Uninstalling CDM

Drivers section of this document for further details of this procedure.

 Download the latest available CDM drivers from the FTDI web site and unzip

them to a location on your PC.

 If you are running Windows XP or Windows XP SP 1, temporarily disconnect

your PC from the Internet. This can be done by either removing the network

cable from your PC or by disabling your network card by going to the "Control

Panel\Network and Dial-Up Connections", right-clicking on the appropriate

connection and selecting "Disable" from the menu. The connection can be re-

enabled after the installation is complete. This is not necessary under Windows

XP SP 2 if configured to ask before connecting to Windows Update. Windows XP

SP 2 can have the settings for Windows Update changed through "Control

Panel\System" then select the "Hardware" tab and click "Windows Update".

 Connect the device to a spare USB port on your PC. If the device is based on

the FT2232, the Microsoft composite device driver is automatically loaded in the

background. Once the composite driver has been installed Windows Found New

Hardware Wizard will launch. If there is no available Internet connection or

Windows XP SP 2 is configured to ask before connecting to Windows Update,

the screen shown in Figure 2.1 is displayed. Select "No, not this time" from the

options available and then click "Next" to proceed with the installation. If there is

an available Internet connection, Windows XP will silently connect to the

Windows Update website and install any suitable driver it finds for the device in

preference to the driver manually selected.
