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.
