Win 10 USB Driver for connecting to CH340 serial to USB chip

I am trying to connect to an Arduino with a CH340 serial to USB chip via my USB port but the computer will not recognize it. I am reading up that it requires a USB driver update for it to work. However, I do not see anything that provides me with a driver
for a Windows 10 PC that only has USB 3.0 ports. Is there a Microsoft USB driver update that will enable connectivity to these boards?

Arduino Uno R3 ATmega328P CH340G board.

 

Installing USB-SERIAL CH340 drivers (Arduino)

Hello

I need to install (remotely) a driver "USB-SERIAL CH340" to allow an Arduino board to communicate with a PC. This driver is used as a serial port over a USB port. Since we are all confined ( Covid-19) , I can't go to his place to help him.

I got access to his PC uing AnyDesk

This driver is installed on my own PC, but I can't find a way to install in on my brother Windows 10 PC.

Any help appreciated
Good luck to all

Martin

Thanks.

Have now got things working in a rather 'round-about' way.

I have 2 USB - Serial Interface cables.

1. The older which used to previously work on Windows 10 still works OK on a Windows XP Laptop proving that the interface is still functional.
2. The newer interface cables when connected to Windows 10 automatically installs the drivers & works on Windows 10, but will not work on Windows XP (I don't have a driver disk for this cable but it is CH340 v3.4.2014.8)
3. If I uninstall all relevant drivers, then install my original Vista Driver v3.2.0. & plug in the interface cable, Windows 10 will then update drivers BUT with Code 10 error. If I now update drivers back to v3.2.0.0 it works & I have a singe interface cable that works on both Windows 10 & Windows XP
   
   
   
   
   
   However, when I unplug the cable & re-insert, Windows 10 will automatically update the drivers to the NON-Working ones & I have to then re-select the v3.2.0.0 ones every time.
   
   Is there a way to stop Windows 10 from updating these drivers every time the cable is inserted?
   I've tried changes the System settings for updates but without success.
