How did you do that? Just removing the device doesn't delete the driver. It just un-links them Sometimes Windows gives you the extra option to do so but if it thinks it's still in use it doesn't.

But if you have the CH340 driver installed, then plug in the CH340 and Windows will just link the driver for you. No need to dig through.inf files.

But the fact you 'installed' FTDI drivers for it I start to think it's NOT a CH340 but just a Chinese/counterfeit FTDI which will install with the latest FTDI drivers but just will not work. Google 'FTDI gate'.

Hello, I am trying to install the CH341/CH340 driver on my windows 10 laptop for my Arduino Nano, but I am not having much luck. When I try to use Window's driver manager (searching automatically online or browsing my computer), the correct driver is found but I get an error trying to install it, shown below. I have also tried both setup applications that I downloaded from the companies website, 'and those both also failed, showing one error the first couple attempts, then another error, neither with much detail but attached below.

After hours of searching online, any help is much appreciated, thanks. Hi, Most USBs (Universal Serial Bus) drives are plug and play ready in Windows 10.

I am trying to install another driver and am getting the same error.

I can keep repeatedly trying to install it, but i'm not sure that it will work, especially as it is not found with the automatic search. This seems to be the primary error, as far as I can tell, error code 1022, 0x000003FE, 'A notify change request is being completed and the information is not being returned in the caller's buffer. The caller now needs to enumerate the files to find the changes'. I would really appreciate some help this time.
