To fully understand why version 3.2.0.0 is so widely sought after, it helps to know the history behind Prolific's driver lockout. PL2303 chips were so successful that they became a target for counterfeiting, primarily by Chinese manufacturers. These counterfeit chips were functionally similar enough to work with genuine drivers, but they infringed on Prolific's intellectual property. In response, Prolific began updating its drivers to detect counterfeit chips and block them from functioning. The detection logic was implemented in driver versions 3.9.x and later. When a counterfeit chip was detected, the driver would deliberately prevent the device from starting, displaying the infamous "Code 10" error message.

The unintended consequence was that many older Prolific chips—particularly the PL2303HXA and PL2303XA models that were discontinued years ago—were also caught in the dragnet because their hardware IDs were not included in the whitelist of newer driver updates. As a result, users who had purchased authentic Prolific products years ago suddenly found their adapters no longer working after a routine Windows Update. The only solution was to revert to a driver version predating the counterfeit detection code. Version 3.2.0.0 fits that bill perfectly, as it was released in 2007, years before the counterfeit problem escalated.
