CH340 Driver Installation Failure Windows 11

Hello, I just moved to windows 11 because Bill Gates told me to do so. In windows 10, I already installed the CH340 driver for my nano and it worked fine. But when I installed windows 11, it uses the FTDI driver. So I tried installing the same ch340 driver. during the installation progress, it went bluescreen LMAO. Has anyone had success installing the CH340 driver in Gate's Windows 11?

Bill Gates said to me that I should install windows 11 on my Arduino. How do I do that?

Bill Gates (Microsoft) said that Windows 10 would be the last version of Windows.

So why did you believe him when he told you to install an operating system that does not exist ?

Yes, I just ran the installer and it worked.

It kept failing for me, maybe because I have installed it before when I was using windows 10. I tried uninstalling but it always says that the device is not connected

tried other drivers

manual install using device manager causes BSOD tried it 10 times

Using Windows 10 (Bill tells me that my computer is too trash to be worthy of 11). I have had the same type of error when running that `SETUP.EXE.

The approach I have used successfully:

  1. Open the page on the Chinese manufacturer of the CH340's website that provides the driver downloads: http://www.wch.cn/downloads/CH341SER_ZIP.html
  2. Click the button with the cloud and downward pointing arrow to download the driver.
  3. Wait for the download to finish.
  4. Unzip the downloaded CH341SER.ZIP file.
  5. Open the Windows Device Manager.
  6. Connect the CH340-based board to your computer with a USB cable.
  7. You should see a new device ("USB2.0-Serial") appear under the "Other devices" section of the device tree. Double click on it.
  8. Click the Update Driver... button.
  9. Click "Browse my computer for drivers".
  10. Click the Browse... button.
  11. Select the unzipped folder of the download from the WCH website.
  12. Click the OK button.
  13. Click the Next button.

The driver should now install successfully. After that, the CH340 -based board should appear in the "Ports (COM & LPT)" section of the Windows Device Manager device tree as "USB-SERIAL CH340 (COMn)" and the board should show up under the Arduino IDE's Tools > Port menu.


I prefer the above approach because I avoid running manufacturer-provided driver installers due to the fact that they (manufacturers in general, not WCH specifically) tend to also install some useless bloatware in addition to the drivers. However, I have also had success (and no apparent bloatware) from this approach:

  1. Open the page on the Chinese manufacturer of the CH340's website that provides the driver downloads: http://www.wch.cn/downloads/CH341SER_EXE.html
  2. Click the button with the cloud and downward pointing arrow to download the driver.
  3. Wait for the download to finish.
  4. Run the downloaded CH341SER.EXE file.
  5. If you get a Windows "User Account Control" dialog, click the Yes button.
  6. In the "Device Driver Install / Uninstall" dialog, click the INSTALL button.

IKR dude, it worked for me in windows 10. but now for some reason, it automatically uses the FTDI driver.


When I try to update the driver to the ch340 one. It went bluescreen. I have tried it like 10 times now.

I asked someone to help in Bill Gates forum. I Hope Bill Gates can help me

installing driver in linux is so hard. I tried it once installing the same CH340 on mint. I gave up lmao it kept using the FTDI driver thing

Looks like this guy found a solution in the end: CH340G Drivers for Windows 11 - #3 by beejayf

I tried it and when I try to install the driver. it went bluescreen IDK why? like the progress bar stuck at 40% then it went bluescreen.

The thing that I also notice is that after uninstalling when I reconnect it, it automatically uses the FTDI driver. when I try to update it to the CH340, it went bluescreen. I'm so frustrated

Oh soo I actually have the FTDI controller not the CH340 thats why. After installing an old driver from FTDI and programming the Controllers' EEPROM I finally got it to work, thanks for all the replies.
