USB Driver Setup

The Windows combined driver model (CDM) may be installed on XP, VISTA, Windows 7 or
Windows 8 allowing applications to access FTDI devices through either the D2XX DLL or a
COM port without having to change driver type. However, it should be noted that an
application can only communicate through one of these interfaces at a time and cannot
send commands to the D2XX DLL and the associated COM port at the same time.
If there is an available Internet connection, Windows will silently connect to the Windows
Update website and install any suitable driver it finds for the device once connected. If an
manual install is desired, follow the instructions below.
Run the CDM.exe driver to install the FTDI based USB.
Click "Continue Anyway" if this dialog box pops up.
The next step is to install the D2xx.dll. While this is a communication port (RS-232)
emulator, no configuration of the RS-232 port is required.
Once installed, the FTDI USB device will show up as a USB SERIAL PORT (COMx) listed
under the "COMM PORTS AND LPT" within Device Manager. The "x" indicates the COMM
port number this will be used for that USB port connection to the printer.
