Hi,
Prolific USB to serial not working on Windows 10 for me...
If any one had tried then please tell me how to make it work. I have to use Windows 7 virtual machine for that.

Did you try with this driver? It claims it can do Win10.
Almost for all chips. There is an utility to check your chip version as well..

:| yes i tried that too...
Converter works smoothly on Win 7 and Ubuntu but not with windows 10.

Code: Select all

This device cannot start. (Code 10)

A device which does not exist was specified.

I got this error in driver details.

I've got 3 prolifics (those blue dongles, PL2303TA inside) and had problems even with Win7.
After messing with several drivers in past it works now (I think the latest driver has been installed automatically, but not sure). Not with all three, one disconnects after some time (~hour).
People say the Win7 and 10 recognize a fake PL2303 and do not allow to install it, or, it switch them off after a while.
There is only one or two chips supported with Win10, afaik.
Btw, this is the driver in my Win7 which works nice.

It is not the OS but the Prolific driver. There was a time when the original drivers bricked the fake chips. Today drivers simply refuses to work with fake chips.

If you install then it work for 1-2 days and after that again it won't.

LOL, fake PL2303 chips as well now ...

I womder how cheap a product has to be, so that its not worth cloning.

On a vaguely related note... There are STM32f103 boards that emulate the CH340g USB to Serial adaptors.
( and also do USB to SPI and USB to I2C) and the firmware binary was posted to another thread...

But the cost of those is about 5 x as much as a CH340g adaptor...


The main problem is of course Windows, which does not provide a easy way to load the built in USB to Serial device driver which has been part of Windows for many years.
