I recently bougth two USB-to-UART converters with Prolific PL2303 chip inside. I found them on Aliexpress in a really good price (0.89$ each).
After waiting 3 weeks, they finally arrived.
But unfortunately I didn’t read enough about converters with these chips before buying. As it turned out converters are recognized in Windows 8.1 as Prolific-to-Serial Comm Port but marked with yellow warning sign.
Putty is constatly giving an error „Unable to open connection”. In addition in the device propperties I found an error

A quick investigation gave an unpleasant anwser – PL2303 chips are fake!
In the newest drivers Prolific blocked all fake chips and the driver in Windows 8.1 is also blocking my fake pl2303.
But there is a solution – you have to install old drivers – version 3.3.2.105.

Simply install drivers, then go to Device Manager -> Right click on Prolific-to-Serial Comm Port and select Update Driver Software….
In Update Driver Software window chose: Browse my computer for driver software -> Let mi pick from list of devices on my computer, Select Prolific USB-to_Serial Comm Port version 3.3.2.105 model [10/27/2008] from model list and click next.

Driver

USB-to-Serial Comm Port Driver.

The driver will install and your fake pl2303 Prolific converter will be ready to use 😉

fabia I - komunikat 'brak sterownika gazu'

Kod 10 z objaśnieniem i do tego żółty wykrzyknik. To z czym się chcesz łączyć jak portu com nie masz? Niestety w takim przypadku nie połączysz się. Odinstaluj sterownik i zainstaluj ponownie pamiętaj by za każdym razem kożystać z tego samego portu. Nie zmieniaj gniazda do którego raz podłączyłeś interfejs diagnostyczny. T masz program do sprawdzenia chipu i sterownik. Całość nowa i powinno pomóc. Po poprawnej instalacji jak w menedżerze będziesz widzieć że wszystko jest w porządku możesz ustawić właściwości portu. To powinno rozwiązać problem.
