Usage example:

While CDM 20814 is a very stable driver, it is quite old. If you are using Windows 10 or Windows 11, or if you have an authentic FTDI chip, it is often better to use the latest available driver (currently v2.12 or newer).

Newer drivers fix security vulnerabilities and improve compatibility with the latest Windows updates. However, for counterfeit chips (often found in cheap USB cables), newer FTDI drivers may intentionally brick the device or cause it to stop working. If your device uses a cloned chip, CDM 20814 is a safer version to use.
