How to install

  1. Check that this is the right driver. Open Device Manager (right-click the Start button), right-click your device, choose Properties and look at "Hardware Ids" on the Details tab. The value should match one of the supported IDs below (more about hardware IDs).
  2. The driver comes as a .cab package. Open Command Prompt as administrator in the download folder and unpack it:
    mkdir C:\Drivers\pkg
    expand -F:* wch-ch341-usb-serial-driver-3.9.2024.09-x86-x64-arm64-e0ad5d1f.cab C:\Drivers\pkg
    (Alternatively, double-click the .cab file, select all files and copy them to a folder.)
  3. Install the driver with pnputil /add-driver C:\Drivers\pkg\*.inf /install. You can also do it from Device Manager: right-click the device, choose Update driver, then "Browse my computer for drivers" and select C:\Drivers\pkg.
  4. Restart the computer and check that the device no longer shows a yellow warning sign in Device Manager.
