Prolific Usb To Serial Windows 10 Not Working

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:

Aug 03, 2016 The older which used to previously work on Windows 10 still works OK on a Windows XP Laptop proving that the interface is still functional. The newer interface cables when connected to Windows 10 automatically installs the drivers & works on Windows 10, but will not work on Windows XP (I don't have a driver disk for this cable but it is CH340. Prolific USB-Serial. 10 automatically installs the drivers & works on Windows 10, but will not work on Windows XP (I don't have a driver disk for this cable but it. Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL (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). And Windows 8, 8.1, and Window 10 are set by default to automatically update your drivers without your permission or even notifying you of the update. So no matter how many times you remove the driver files and reboot, the next time you insert the USB-To-Serial adapter, Windows installs the newest non-working version again. Yes, it’s frustrating.

Dec 22, 2015 Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL (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). Nov 27, 2015 Now Includes Windows 8.1 and Windows 10! Download this driver for installing and fixing of prolific usb to serial driver windows 10 code 10. U will get such kind of errors when you try to install pl2303 drivers in win 8 and win 10.

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 !!!

Install Prolific Usb To Serial

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..
