Prolific USB to Serial Driver (Windows 11/10/8.1/8/7)

Many of the USB to Serial cables on the market use Prolific chipset, these chipsets do require drivers to be installed for reliability and compatibility. As this device converts a serial connection usually in the form of a RS-232 based com connector to a more modern high speed USB type serial the drivers are going to need to be installed correctly. Even though the latest drivers are recommended some users report better stability and compatibility using older versions of drivers on older systems running Windows 7 and lower. The best thing to do is install the latest unless a told to install an older version.
