PROLIFIC USB-TO-SERIAL COMM PORT WINDOWS 10 - Microsoft Community

PROLIFIC USB-TO-SERIAL COMM PORT WINDOWS 10 - Microsoft Community:



'via Blog this' Tested on W10 family and pro, 32/64 bits.

The solution for old PL-2303 HXA/X : use a driver release older than 3.4.

Edit: The procedure above works, but only temporary. Each time you turn your computer off, the latest driver is reloaded due to windows auto-update (or if you unplug and plug again the device into USB port).

To avoid that, a recent turnaround exist and has been published by Microsoft. It's a tool named wushowhide.diagcab ("Show and Hide Update"). It allow to inhibit the auto-update for a particular program or driver (Prolific in our case).
For more informations and where to download this tool, take a look at this article :KB3073930

I have tested it and it work fine. The only problem with it, is that, it reload the latest driver when you plug the device on a never used USB port. So, if you change place of connection, you should manually set the driver to 3.3, but you have to do that only the first time you used this port. Next time, the driver remain to 3.3 and never upgrade to 3.6.
