Prolific Usb To Serial Comm Port Version 32 00 Download 2021 [verified] Page

The Prolific USB-to-Serial Comm Port driver version 3.2.0.0 is an older driver, originally dated July 31, 2007, which is frequently used as a workaround to fix compatibility issues with certain USB-to-serial chips (often clones or discontinued models) that no longer work with newer drivers on modern operating systems like Windows 10 or 11. Why This Version is Popular

Users often seek this specific version because newer "official" drivers may trigger a "Code 10" error or display a "Phased Out" message if they detect non-original or older Prolific PL-2303 chips. Downgrading to version 3.2.0.0 often restores functionality for these devices. Where to Download

Since this is an older version, it is typically found on enthusiast sites or manufacturer support pages rather than the main Prolific corporate site:

Enthusiast Sites: Sites like Miklor and VE7ED provide direct links to version 3.2.0.0 for radio programming and other legacy uses.

Manufacturer Support: Legacy support for specific hardware brands, such as Dell, may offer specialized installers, though they often host newer versions like 5.1.x or 5.2.x.

Official Prolific Site: You can access their current driver downloads at Prolific USA or via their Customer Login (using GUEST for both username and password) to see if they still offer legacy versions.

Step 3: Installation Guide (How to Force a Specific Version)

If you are stuck with a "Code 10" error or want to downgrade to a working version:

1. Download the Driver: Ensure you have the installer or extracted ZIP file for the older driver (e.g., v3.3.2.102).
2. Uninstall Current Driver:
   • Go to Device Manager.
   • Right-click the Prolific device -> Uninstall device.
   • Crucial: Check the box that says "Attempt to remove the driver for this device" (or "Delete the driver software for this device"). Click Uninstall.
   • Note: You may need to do this multiple times if Windows keeps reinstalling it automatically.
3. Install Your Downloaded Driver: Run the PL2303_Prolific_DriverInstaller.exe (or equivalent) you downloaded.
4. Restart your computer.
5. Verify: Check Device Manager. It should say "Prolific USB-to-Serial Comm Port" without a yellow exclamation mark.

Step-by-Step Guide: Prolific USB to Serial Comm Port Version 32.00 Download (2021)

Because Prolific removed older driver links from their main website after 2022, finding the authentic version 32.00 from 2021 requires careful navigation. Do not download from random driver update websites—they often bundle malware.

Final Caution (Important)

If you still need this specific driver today, always scan the downloaded .exe or .zip with VirusTotal or Windows Defender. Many sites claiming to offer “PL2303 v3.2.0.0” actually bundle malware. When in doubt, use the Windows Update Catalog or Microsoft Update — Prolific drivers are often pushed through Windows Update as optional updates.

Why 2021 Users Needed Version 32.00 Specifically

Throughout 2020–2021, three major changes disrupted industrial and hobbyist users: Step 3: Installation Guide (How to Force a

1. Windows 10 Version 20H2/21H1 driver enforcement: Microsoft began blocking unsigned or older drivers. Version 32.00 was one of the last to be cross-signed for both legacy and new kernels.
2. Shift to PL-2303GC revision: Prolific launched the GC chip in 2021, which requires entirely different drivers (v1100+). Version 32.00 does not support GC. If you bought a new adapter in 2021 with a GC chip, you cannot use this driver.
3. End of support for PL-2303H (original): The original 2004-era PL-2303H (non-X, non-XD) lost all driver support after 2021. Version 32.00 is the last driver that partly works with H chips under Windows 10 with reduced baud rates (max 115200 instead of 12M).

Thus, the search for "Prolific USB to Serial Comm Port version 32.00 download 2021" was mainly driven by owners of older but genuine PL-2303 HX, HXD, and EA adapters who refused to upgrade hardware.

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:

• 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.
