Chances are the chipset in your converter is not compatible with Windows 10. You need a Prolific 2303HX Rev.D chipset. Auto download of the driver is available but without the chipset it won't work. Good Luck!

Yes, I believe you are correct that my chipset is not compatible with Win10. Obviously obtaining a new adapter would remedy the issue. However, late at night or if you do not want to be bothered with obtaining a new adapter for something you very infrequently use, downloading the 3.3.3.114 driver dated 2009, installing the driver and rolling the driver back to this 2009 driver for the comm port your connecting the outdated adapter to, does allow you to finish your work without delay.

What I was doing with the Serial/USB adapter was programming a new Motorola two way radio so it could be used in our network. This is a task is something done very infrequently. Finding a way to use my existing serial/USB adapter allowed me to accomplish what I needed to do without waiting to find an adapter supported by Win10.

Hope this helps others that may also be in a bind. I have since, at my leisure, purchased a new Serial/USB adapter supported by Win10 so I can use the programming cable necessary to program any new radios we obtain in the future.

Hi,

I'm afraid that there is no solution..
There is lot's of people reporting problems with W10 and Prolific devices (based on popular PL2303 adapter).
Myself, I've the same problems with scrolling LED Badges, and USB to COM dongles. 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). When you plug the device into USB, it is well recognized by W10 and it try to load the Prolific driver. This work fine, but looking at the configuration panel, you will then notice that there is an error code 10 and the driver is not working properly.

Of course, you can try to manually update the driver at Prolific site:

But, look carefully on this page and you will read an important notice in RED :

Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303XEOL (End Of Life) chip versions.

This is clear: if your device is using an old chip version of PL2303, the drivers not works with W10 (and W8). Download win 10 pro.

As many people, you probably upgrade directly from W7 to W10, and sure, don't know that this problem was already present with W8. It's a shame from Prolific to not support this devices, because they are still used (my LED badges are less than a year old, and use EOL PL-2303 HX). Prolific's guys are fun when they said : 'Prolific recommends to use PL-2303HXD (HX Rev D) or PL2303TA chip.' . Hey, but I can't do that myself !!!

I don't want to send my devices to trash because they are too old (less than a year !) to be supported by W10.
May be, a solution will be to use the old W7 drivers version into W10. Not tested.. I will try..
