The driver should now install successfully. Select the folder of the unzipped CH341SER.ZIP you downloaded from the WCH website.Click "Browse my computer for drivers".You should see a new "USB2.0-Serial" device appear under the "Other devices" section of the device tree.Connect the CH340-based board to your computer with a USB cable.Click the button with the cloud and downward pointing arrow.

zip file and install the drivers via Windows Device Manager because some driver installers also install additional applications to manage that device and I only need the driver itself in this case. I actually think I have only ever used the driver installer once. I had not, but I just gave it a try and had the same problem as you. Have you tried it on one of the later feature updates on Win10? But, I've searched quite a bit (over the last 2 hours) and I keep winding up on the same threads from 4 years ago, nothing more recent is coming up & those solutions are not working. I apologize if this has been recently covered. I've had other issues with programs being blocked with no option to unblock them in the past few months leading to large amounts of frustration. I suspect Microsoft's recent over-enthusiastic "protect users from themselves" Apple mentality is to blame. I also tried on my main PC (also newer than the last time I tinkered with an Arduino) and it's also failing here with the same nondescript error. I've tried compatibility mode and disabling driver enforcement (as recommended on this forum as far back as 2017), but nothing is working. The installer will launch, but when I click the install button I get "Driver install failure!"
I've downloaded several times from multiple sources. I know I need to install the driver for the CH340 controller to work properly, but I can't seem to install it.

In this case, the error appeared on a Linux when trying to upload code due to the drivers not being installed and the root permissions.I've got an old laptop (2nd gen i7) with a fresh install of Windows 10 Pro 21h1 that I'm using in my new workspace to get back into tinkering, which I haven't done in several years. language:bashĪvrdude: ser_open(): can't open device "/dev/ttyUSB0": No such file or directory You may receive an avrdude: ser_open(): can't open device error similar to the output shown below.

If you installed the drivers for the CH340 on your computer but have issues connecting via serial terminal or uploading code using the Arduino IDE, there may be an issue with your user settings preventing you from using the CH340. COM Port Not Available Windows, Mac, and Linux Users seem to be able to eventually get the board recognized by a combination of giving the computer time to finish the install ( close to 20 min), plugging the board back in multiple times, reinstalling the drivers, and/or resetting the computer multiple times ( repeat both steps). Others have had issues where the installation process hangs.īased on the customer experiences, this might be specific to the manufacturer and are usually isolated cases. However, the board cannot be accessed on the Arduino IDE. We have had a few reports on Windows 10 where the driver will automatically install and the board will show up under a new COM port as USB-Serial CH340, but with a different device name.
