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.

If your adapter worked with Windows 7 but fails after installing v3.2.0.0 (showing Code 10 or This device cannot start ), it almost certainly contains an unsupported older or counterfeit PL2303 chip.

: For users who own adapters with modern PL2303 chips (GC, GS, GE, GT), none of the legacy workarounds are necessary. Prolific continues to release official drivers for these chips, with version 4.0.8, 4.6.0.0, and 5.2.7.2 all available for Windows 10/11 as of late 2024 and early 2025. If your adapter uses one of these newer chips, you should download the latest official driver from Prolific's website rather than using version 3.2.0.0.
