The Prolific USB-to-Serial Comm Port Driver (Version 3.2.0.0) is widely regarded by technical communities as the "gold standard" fix for older or clone PL-2303 hardware that has been rendered non-functional by newer Windows updates. The "Save-Your-Hardware" Driver
This specific 2007-era driver is the go-to solution for the notorious "Code 10: This device cannot start" error.
Anti-Counterfeit Workaround: Newer Prolific drivers are designed to detect and disable "counterfeit" or clone chips, which are common in budget programming cables. Version 3.2.0.0 does not include these checks, allowing many "unauthorized" cables—such as those used for ham radios like Baofeng—to work again.
Legacy Compatibility: It is specifically recommended for older PL-2303HX and PL-2303HXA chipsets that the manufacturer has officially marked as "End of Life" (EOL). Performance and Reliability Windows 11 Prolific Driver Setup

In recent years, Prolific implemented driver-level checks that disable older PL2303 hardware (like the PL2303HXA or PL2303XA). When these chips are used with modern drivers, Windows may display a yellow warning triangle or change the device name to "PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER". misc.daniel-marschall.de Version 3.2.0.0

The Prolific USB-to-Serial Comm Port Driver version 3.2.0.0 is widely recognized as a "legacy" or "golden" version required to restore functionality to older or cloned PL2303 chips on modern operating systems like Windows 10 and Windows 11. Why Version 3.2.0.0 is Critical
Manufacturers often use older PL2303 chipsets (such as PL2303HXA or PL2303TA) that Prolific has officially phased out (End of Life).
Driver Disablement: Newer drivers (e.g., version 3.9.1.0 or later) automatically pushed by Windows Update detect these older or "counterfeit" chips and disable them, showing errors like "Code 10" or the message "PL2303TA DO NOT SUPPORT WINDOWS 11 OR LATER".
Compatibility Workaround: Version 3.2.0.0 (originally released around 2007–2008) does not include these hardware-disabling checks, allowing older and cloned hardware to function normally on Windows 10 and 11. Where to Download (2021/2022 Sources) Conclusion: Preserving Legacy Hardware with Version 32
Because Prolific no longer hosts these legacy versions, you must use reputable third-party archives or manufacturer support pages:
Miklor (Radio Support): Highly recommended for programming cables; provides direct links to 3.2.0.0.
Family Software: Provides a fix package that automates the installation of compatible legacy drivers.
Gorse.ca: Offers a direct ZIP/EXE download of version 3.2.0.0 for 32-bit and 64-bit systems. Installation Steps for Windows 10/11
To successfully use version 3.2.0.0, you must manually "roll back" the driver to prevent Windows from auto-updating it:
Prolific Technology Inc. makes the PL2303 chipset, one of the most common USB-to-serial bridge controllers. It’s used in countless cables and adapters to connect older serial (RS-232) devices — like routers, GPS receivers, industrial scales, and programming tools — to modern computers without a built-in COM port.
Prolific intentionally disabled older, counterfeit PL2303 chips in drivers released after ~2012–2013.
If your adapter uses an unofficial (clone) chip, any driver newer than v3.3.x will show Code 10 (device cannot start).
That’s why people search for version 32 00 (3.2.0.0) — it’s one of the last versions that still works with many clone chips, especially on Windows 7, 8, and early Windows 10.
