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).
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...

When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
- Serial cables
- Serial ports
- Serial devices
To test your setup components, try the following:
- Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.
- Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Map Usb To Com1
- Test each cable individually.
- Use short cables when you are testing.
When you test the serial ports and serial device, it is recommended that you do the following:
Com1 Port
- Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).
- Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.
- If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows - If the device is listed with an error, follow the instructions on the website to reinstall the drivers.
Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.
