Hi to all, here are the drivers that work perfect on windows 11 and 10.

Happy fixing

Have you tested the software on Windows 11 ?

There were some customers who said they cannot install the driver on Windows 11.

@azzido 100% install the drivers I have provided and because they are latest from pl2303 windows won't update again and the programer will 100% on windows 11 and 10. Kind regards

@susanasense 

Can you take a picture from Windows 11 with PL2303 driver in Device Manager or whatever it is called in windows 11 ?

@azzido will do soon I get home. Regards

@azzido Hi, here is the screenshot

Great. Thank you for sharing this info.

@azzido no problem, windows 11 always updates drivers if newer cones out if the software don't see the programer it's easy just removed the recent update driver by windows 11 and all will work perfect. The drivers I provide are from the pl2303 maker so the latest for Windows 11 and 10. Regards

Both the links above are redirecting back to the home page of prolific : https://www.prolific.com.tw/US/index.aspx

Would anyone have a link direct to the Windows 11 drivers?

OK, I did a search on the internet and recommandation was to find an older version of the Prolific driver (V 3.9.1)

https://techcommunity.microsoft.com/t5/windows-11/pl2303-issues-prolific-usb-to-serial-drivers-win-11/m-p/2966957

Searched my hard drive and found

PL23XX_Prolific_DriverInstaller_v206

This installed driver version V3.8.39 (slightly older than 3.9.1 but hey I am desperate) and it is now working with Windows 11!

Final update on my side on this topic, I have managed to get hold of the drivers version 3.9.1 from the Prolific website
https://www.prolific.com.tw/UserFiles/files/PL23XX_Prolific_DriverInstaller_v401(1).zip

and this DOES NOT work for me on my Windows 11 machine, I had to re-install the older version 3.8.39 which works a charm on my setup!

Why did I reinstall again, well it looks like Windows 11 did an automatic update of the driver for me to V3.9.3 and that didn't work too well either for me.

Version 3.9.0.2 from here also works : https://deviceinbox.com/download/chipset/Win11_DCHU.zip

this is an INF / CAT install version (right click on the INF and select 'install'

Thanks for sharing this info.

Can you please test the same driver version on Win7, 10 and 11 ? If we find a Prolific driver working on all 3 Windows versions I can include it in the setup.

@azzido i cant even get the driver from the link, it just spinning me in circles

@Nicusor, I don't think I still have a Win7 machine, I should be able to find a Win10 machine over the week-end.

One more step needed is to disable the automatic Windows 11 driver update!

Every morning my Prolific driver was getting updated (including this morning! Grrr!) so no more comms with the NLBA box.

This will hopefully do the trick : https://pureinfotech.com/disable-automatic-driver-install-windows-11/

For reference, I attache the 2 drivers that work for me to this message. Only one is needed, just that they have different install methods (one is .exe and the other is right click on the INF), if you run the .exe version and you already have another version of the driver it will ask you if you want to uninstall (which I usually do) and then run again the .exe to install the driver.
