Prolific 3.3.2.105 ^new^

Newer official drivers (versions 3.4 and above) intentionally trigger a "Code 10" error if they detect a non-genuine Prolific chip. Version 3.3.2.105 often allows these clone chips to function correctly, making it a preferred choice for users troubleshooting USB programming cables (e.g., Baofeng, Kenwood, Yaesu radio cables).

Upgrade notes

The Prolific PL2303 chip family is one of the most widely used USB-to-UART bridge controllers in the world. It connects everything from microcontrollers and network switches to GPS receivers and amateur radio gear directly to modern PC hardware. Technical Details: Release Date: October 27, 2008

Driver version 3.3.2.105 is a powerful tool for fixing "Code 10" errors on counterfeit PL2303 chips, but it comes with risks.

Because driver version 3.3.2.105 predates these chip-checking restrictions and digital signatures, it lacks the mechanisms that intentionally reject legacy or clone hardware. Installing it allows the operating system to process input/output data seamlessly through the USB-to-Serial Bridge without throwing errors. Step-by-Step Installation Guide
