This category gathers official and legacy drivers for Prolific USB-to-serial chipsets used in adapters, serial printers, barcode scanners, POS terminals, GPS units and other COM-port devices. You’ll find PL-2303 family packages, WHQL-signed installers for modern systems, older releases for legacy hardware revisions, and platform builds for Windows, macOS and Linux. Each download entry lists chipset revisions, supported OS architectures (32/64-bit) and file sizes so you can match the correct package.
Installation notes are provided with every file: remove existing drivers first, choose the installer or manual INF update via Device Manager, and reboot after installation. Compatibility tips explain how to identify chipset IDs, assign COM port numbers and address common issues like unsigned-driver warnings or counterfeit-chip limitations. Use the search filters to pick the right chipset revision and OS build before downloading; follow the included readme for a smooth setup and quick device recognition.
