Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL (End Of Life) chip versions. Of course, you can try to manually update the driver at Prolific site:īut, look carefully on this page and you will read an important notice in RED : This work fine, but looking at the configuration panel, you will then notice that there is anĮrror code 10 and the driver is not working properly. You plug the device into USB, it is well recognized by W10 and it try to load the Prolific driver. All this devices use a PL2303 to provide a connection to an USB port, but inside, they are RS232-like interface build (and appear as a COM port in your operating system). Myself, I've the same problems with scrolling LED Badges, and USB to COM dongles.

There is lot's of people reporting problems with W10 and Prolific devices (based on popular PL2303 adapter).
