Prolific | 3.3.2.105

Released around 2012–2014, version 3.3.2.105 was significant because it worked reliably on systems, bridging the gap between older hardware and newer OS versions. It was one of the last drivers before Prolific began actively blocking counterfeit chips (many low-cost adapters used cloned PL-2303 HX/HXA/EA chips) in later driver releases.

Some third-party driver repositories host this file, but always verify checksums and run antivirus scans before installation.

Demystifying Prolific 3.3.2.105: The Definitive Fix for PL2303 USB-to-Serial Errors

Here’s what I can tell you based on database and IT release pattern analysis:

: Authentic older hardware using early PL-2303HXA and PL-2303XA chips was also phased out. Modern drivers explicitly trigger messages like PL2303HXA PHASED OUT SINCE 2012 . The 3.3.2.105 Solution prolific 3.3.2.105

Windows may automatically replace version 3.3.2.105 with a newer one. You can prevent this by disabling automatic driver updates through Group Policy or the System Control Panel.

Despite being nearly two decades old, the 3.3.2.105 driver remains relevant. Here’s why:

However, many users encounter issues with newer drivers, specifically receiving "Code 10" errors on Windows 7, 8, 10, and 11. This is where (often dated from 2008 or 2009) becomes critical. This article provides an in-depth guide to version 3.3.2.105, explaining why it's used, how to install it, and why it remains a preferred solution for specific hardware.

, making it the "go-to" driver for older hardware. Released around 2012–2014, version 3

: The emphasis on security and stability in Prolific 3.3.2.105 has raised awareness about the importance of data protection, encouraging other software developers to prioritize these aspects.

: This version offers improved data handling capabilities, allowing users to efficiently manage large datasets with ease. The software provides a user-friendly interface for data manipulation, filtering, and analysis.

Even after installing, Windows may still use the wrong version. You must force it to use 3.3.2.105:

: Because Windows 10 and 11 constantly try to "fix" the driver by updating it back to the non-functional newer version, users often have to use scripts or third-party "Code 10 Fix" tools to force version 3.3.2.105 to stay installed. Demystifying Prolific 3

The Prolific PL2303 is one of the most common chipsets used to bridge the gap between modern USB ports and older RS-232 serial interfaces. However, a major rift occurred when newer Windows updates began automatically installing drivers that intentionally disabled older or "cloned" (counterfeit) chips. is highly sought after because:

Even with the correct driver, you might encounter a "NO connection" error during hardware updates (such as updating firmware on flight instruments or radios).
