Prolific Usb Serial Adapter Driver

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.

Usb Serial Adapter Driver Software

Europe’s most creative and innovative brand in consumer electronics connectivity for more than twenty years. This is the RS232 driver for the USB adapter. In order to setup the driver you need to download the correct USB driver file and run the installer in the file. Once this has been installed you then need to reboot the computer. Once this is done plug the USB into the adapter.

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).

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..

After upgrading to Windows 10 from 8.1 on my Surface Pro 3 the Prolific RS232-USB driver is not functional as it was under Windows 8.1. The device manager reports for this device:

'This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

Object Name already exists.'

I followed all on-line advice for Code 31 and to no avail deleted the current driver and re-install, re-boot, and search for new hardware it does not fix the problem. I find hints of the driver in the Registry but removing mention of the Prolific device may be problematic since it seems there are other devices I use regularly where removing the entry in the Registry may cause other issues.

As a further comment that is food for thought by Microsoft is that I find the lack of registry repair tool as available in Windows 7 is not a good move by the Technical Staff of Microsoft. You will never get full traction with Windows 10 unless the tools are in place for users to fix problems caused by Windows 10 install to be fixed easily.
