| · | 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 FT2232C Devices section of this document for further details of this procedure.
|
| · | Download the latest available FTCD2XX drivers from the FTDI website and unzip them to a location on your PC. Please note that attempting to install the FTC combined D2XX and VCP driver will result in an unsuccessful installation if the device EEPROM is configured for D2XX drivers.
|
| · | Connect the device to a spare USB port on your PC. As the FT2232C is a composite device, the Microsoft composite device driver must be loaded first. This is not done automatically under Windows 98. The Windows Add New Hardware Wizard will detect the new USB device as a composite device and will guide the user through the installation. Click "Next" on the screen below to continue with the installation.
|
| · | Select "Search for the best driver for your device. (Recommended)." as shown below and then click "Next".
|
| · | Check the box next to "Specify a location" and uncheck all others as shown below. Normally, Windows will find the composite driver already available in the system. If the composite driver is not available on the PC, the "Microsoft Windows Update" option may be selected and a composite driver will be downloaded from the Microsoft Windows update website.
|
| · | Windows will display a message indicating that a composite driver file has been found. In the case below, Windows has found a newer version of the composite driver already installed. It is safe to install this. Continue by clicking "Next".
|
| · | To install the composite driver click "Next".
|
| · | Windows should then display a message indicating that the composite driver installation was successful. Click "Finish" to complete the composite driver installation.
|
| · | Once the composite driver is installed, the Add New Hardware Wizard will then detect a port of the FT2232C device. Windows may display a message reading "Building driver database" at this point which may take a few minutes to pass. Click "Next" when the screen below is shown.
|
| · | Select "Search for the best driver for your device. (Recommended)." as shown below and then click "Next".
|
| · | Check the box next to "Specify a location" and uncheck all others as shown below. Click "Browse" and locate the driver files. Once the files have been located, click "Next" to proceed with the installation.
|
| · | Windows may display a message reading "Building driver database" at this point which may take a few minutes to pass. Once Windows has found the required files, click "Next" to install the device.
|
| · | Windows should then display a message indicating that the installation was successful. Click "Finish" to complete the installation.
|
| · | As the FT2232C has 2 ports available, the second port must also be installed. Under Windows 98, this will occur automatically.
|
| · | Open the Device Manager (located in "Control Panel\System" then select the ""Device Manger" tab) and select "View devices by connection". The device appears as a "USB Composite Device" connected to a USB port with ports A and B respectively denoted as "FTCUSB.SYS FTDI Dual 232A USB Test Board" and "FTCUSB.SYS FTDI Dual 232B USB Test Board".
