Prolific creates the chip designs for these adapters. Over the years, many third-party manufacturers began producing "clone" chips that act like Prolific chips but aren't genuine.

At its heart, the Prolific driver is software that works with the Prolific PL-2303 chip, a common component found inside USB-to-serial converter cables. When you plug one of these cables into your computer's USB port, the PL-2303 chip creates a new virtual serial port (commonly labeled as "COM3," "COM4," etc.) in your operating system. The device then appears as a standard serial port to your software programs, which is exactly what legacy applications expect to see.

Note: This stops Windows from updating all device drivers, meaning you will need to update graphics cards or audio drivers manually. Method C: Use Group Policy (Windows Pro/Enterprise) Plugging the adapter into a different USB port

The solution is to follow Method 1 described above and force the installation of an older legacy driver , such as version 3.3.3.114, 3.3.2.102, or similar.
