Windows: Primary target — Windows 7 through Windows 10 (as of 2021). Behavior on Windows 11 depends on Microsoft driver signing changes; installers claiming WHQL may work but some legacy PL2303 variants required older signatures.
macOS/Linux: Prolific’s official package is Windows-focused; for macOS and Linux users, open-source or OS-provided kernel modules are typical alternatives (macOS driver availability changed frequently in 2020–2021).
Chip variants: Works best with authentic Prolific PL2303 chips. Many low-cost adapters use counterfeit or clone chips that are intentionally blocked by later Prolific drivers; those adapters may be incompatible or forced into reduced functionality.
