4. Creating a Custom Driver

This section describes how to create a custom driver. To

begin, choose the type of installation to customize:

“Virtual COM Port Driver Installation” or “USBXpress

Installation”. Differences between the two installations

are noted, but a sample CP210x customization is

shown in the figures. Next, determine if an installation

executable should be generated (see “4.5. Installation

String Options” and “4.8. Generation Directory” for more

information on the generated installer), and click Next.

4.1. Driver Certification Warning

The first screen is the warning explaining that the

generated driver installation will not be certified. (See

Figure 2.) Click Next to begin customizing your driver

installation.

4.2. Operating System Selection

The first step in the customization utility (shown in

Figure 3) is to specify the operating system for which

the custom driver is being generated.
