is a legacy driver often required for older PL2303 chipsets (like the PL2303HXA) that are no longer supported by newer Windows 10 and 11 official drivers. Using this specific version is a common fix for the "Code 10" error, where newer drivers intentionally disable counterfeit or phased-out chips. Why You Need Version 3.2.0.0
Newer Prolific drivers (v3.8 and above) include security checks that cause older or "phased-out" chips to stop working, often displaying a yellow exclamation mark in the Device Manager. Version 3.2.0.0 is the most stable "backdated" driver that maintains compatibility with these older devices on modern operating systems. How to Download and Install
While Prolific's official website now hosts much newer versions (like v4.0.8), version 3.2.0.0 can still be found through specialized hardware and radio community sites. Microsoft Community Hub

Executive Summary
If you are attempting to download and install the Prolific USB-to-Serial driver in 2021 or later, you likely encountered the "Code 10" Error (This device cannot start). This is not a malfunction of your hardware, but a software conflict intentionally introduced by Prolific.
The Problem: There is a massive market of counterfeit Prolific chips (PL2303) used in generic USB-to-Serial cables. To combat this, Prolific updated their drivers (versions 3.4 and higher) to detect fake chips. If a fake chip is detected, the driver disables the port, causing it to stop working.
The Solution: Downgrading the driver to Version 3.2.0.0 (dated roughly 2007-2009) is the industry-standard fix. This older driver does not contain the anti-counterfeit detection logic and works perfectly with both genuine and generic cables.
Scenario B: You have a Generic/Amazon/eBay Cable (Most Common)
If you try to install the 2021/2022 drivers, your device will stop working.
- The Solution: You must install an older driver (usually from 2009-2012).
- Recommended Version:
v3.3.2.102orv3.3.5.122. - You can often find these on trusted electronics forums or the manufacturer page of the specific adapter brand (e.g., Tripp Lite, Plugable, StarTech often host older drivers).
The Driver Version 3.2.0.0
Released around early 2021, driver v3.2.0.0 for Windows (10/11) was part of Prolific’s ongoing effort to support newer operating systems while blocking counterfeit chips. Key features of that version: prolific usb to serial comm port version 32 00 download 2021
- Windows 10/11 compatibility (64-bit).
- Improved stability for high-speed baud rates (up to 6 Mbps).
- Fixed a blue-screen issue seen in earlier 2020 builds.
- Continued enforcement of counterfeit detection — if your adapter uses a fake PL2303 chip (common in cheap cables), the driver would mark it with a code 10 error (device cannot start).
The Legacy
By late 2021, Prolific had released v3.4.0.0 and v3.5.x drivers, but v3.2.0.0 remained popular because it struck a balance — newer than the very old drivers (which Windows Update might block) but before more aggressive counterfeit blocking in later versions.

- Overview
- The Prolific PL-2303 series enables USB-to-serial (RS-232) connectivity through a virtual COM port. Version 3.2.0.0 is a 2021 driver release commonly used on modern Windows systems. Use the correct driver for your specific PL-2303 chipset (PL-2303HX, PL-2303TA, PL-2303XA, etc.).
- Before you begin — prerequisites
- Identify your device: check markings or vendor documentation for PL-2303 chipset model.
- Confirm Windows version (Windows 7, 8, 10, 11) and whether OS is 32-bit or 64-bit.
- Back up important system restore point before changing drivers.
- If possible, obtain vendor-provided driver first (from the device manufacturer).
- Safe download sources and verification
- Prefer official sources: Prolific’s official site or the device OEM.
- If Prolific’s website or OEM site does not host version 3.2.0.0, reputable archives or Microsoft Update Catalog may have the package. Avoid random file-hosting sites.
- Verify file integrity: compare file size and digital signature when available. In Windows, check file Properties → Digital Signatures and verify signer.
- Note: some older Prolific drivers were removed or restricted by vendors due to counterfeit-chip compatibility — ensure the driver supports your specific chip.
- Installation steps (Windows 10/11)
- Download driver package (exe or zip containing .inf/.sys files).
- If downloaded as zip: extract to a known folder.
- (Optional) Disable driver signature enforcement temporarily only if the driver is unsigned:
- Restart PC → hold Shift and click Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → press 7 (Disable driver signature enforcement).
- Install:
- If installer .exe: run as Administrator and follow prompts; reboot when prompted.
- If only .inf: open Device Manager → find the USB Serial Device (often under "Other devices" or "Ports (COM & LPT)") → Right-click → Update driver → Browse my computer → Let me pick → Have Disk → point to .inf → Install → Reboot.
- After installation, Windows should enumerate a "Prolific USB-to-Serial Comm Port (COMx)".
- Verifying the driver and COM port
- Open Device Manager → expand "Ports (COM & LPT)" → confirm "Prolific USB-to-Serial Comm Port (COMx)" exists and has no warning icon.
- Right-click device → Properties → Driver tab → confirm Driver Version (look for 3.2.0.0) and Provider.
- Note COM port number and configure baud/parity/stop bits in your terminal software (PuTTY, Tera Term, RealTerm).
- Common problems and fixes
- Device shows as unknown or with error code 10/31:
- Reinstall driver using the correct .inf; try a different USB port (avoid unpowered hubs).
- Try removing device (Device Manager → Uninstall device, check to delete driver package) then reinstall.
- Driver blocked by Windows (code 52 / unsigned):
- Use a signed driver. If none available, temporarily disable signature enforcement to install (see step 4). Re-enable enforcement after install by rebooting normally.
- “This device cannot start (Code 10)” after installing 3.2.0.0:
- Confirm chipset compatibility. Some counterfeit PL-2303 chips are incompatible with newer official drivers; try older driver versions known to work with clones (but only from reputable sources).
- COM port number conflicts:
- Device Manager → Ports → Properties → Port Settings → Advanced → Change COM Port to an unused number.
- Frequent disconnects:
- Try a different USB cable, avoid USB hubs, update system USB controller drivers, use powered USB ports.
- Driver repeatedly reverts or Windows auto-updates driver to an incompatible version:
- Block automatic updates for the device via Group Policy or Device Installation Settings in Control Panel, or install signed driver via Administrator with driver package pinned.
- Uninstalling / rolling back drivers
- Device Manager → Properties → Driver tab → Roll Back Driver (if available) or Uninstall Device (check “Delete the driver software for this device”), then reboot and reinstall desired version.
- Clean up driver store: use pnputil to delete driver packages if necessary:
- List drivers: pnputil /enum-drivers
- Delete by published name: pnputil /delete-driver oemXX.inf /uninstall /force
- Notes on counterfeit Prolific chips
- Many third-party cables use counterfeit PL-2303 chips that only work with older Prolific drivers; newer official drivers may intentionally block these devices.
- If you suspect a counterfeit chip:
- Try an older driver version known to work with clones (research reputable source).
- Safer alternative: buy cables from reputable vendors that explicitly state genuine PL-2303 chips or use USB-to-RS232 adapters based on FTDI or CP210x (Silicon Labs) chips with robust driver support.
- Security and compatibility considerations
- Prefer digitally signed drivers from official vendors or Microsoft Catalog.
- Avoid downloading drivers from untrusted file-sharing sites.
- Keep system restore point or full backup before installing unsigned/older drivers.
- If you must use older unsigned drivers, re-enable signature enforcement after installation.
- Appendix: quick reference commands (Windows)
- Show devices: devmgmt.msc
- List driver packages: pnputil /enum-drivers
- Delete driver package: pnputil /delete-driver <oem#.inf> /uninstall /force
- Disable signature enforcement (temporary): Advanced Startup → Troubleshoot → Startup Settings → 7
- Check digital signature: Right-click driver file → Properties → Digital Signatures

The "Code 10" Fix: It is widely used to resolve the "This Device Cannot Start (Code 10)" error caused by newer drivers intentionally disabling non-genuine or older chips.
Stability: Once successfully installed and "locked" against Windows updates, it provides a stable bridge for devices like Baofeng radios, GPS units, and industrial serial equipment. Ease of Installation
Fixing the Prolific USB-to-Serial "Code 10" Error: A Guide to Driver Version 3.2.0.0
If you have tried to connect an older Prolific USB-to-Serial adapter recently, you have likely encountered the dreaded yellow warning triangle in Device Manager or a "This Device Cannot Start (Code 10)" error. This usually happens because Windows automatically updates your driver to a newer version that intentionally lacks support for legacy or "phased out" PL2303 chips.
The most reliable solution as of 2021 is to manually "backdate" your driver to Version 3.2.0.0. Why Version 3.2.0.0?
Newer drivers (often versions 3.8.x and above) are designed for the latest chip revisions and will often block older hardware. Version 3.2.0.0 is widely recognized as the "magic" legacy driver that restores functionality for older PL2303 HXA/XA and TA/TB chips on Windows 10 and 11. Step-by-Step Installation Guide
To get your adapter working again, follow these steps to force Windows to use the older driver version: Prolific USB-to-Serial Comm Port (COM4) Driver for System
6. Better Alternatives for 2025+
If your adapter is blocked by v3.2.0.0:
- Replace the adapter – Buy a genuine FTDI FT232R or Silicon Labs CP210x adapter. These have no counterfeit lockout and are actively supported.
