Error : No DFU capable USB device available

Official Hardware Nano Family Nano ESP32

Hello , I just got a nano ESP32, I use the arduino Cloud editor. I have win v10. When I connect the board, Arduino Cloud identifize it on COM 7. The device manager detect USB COM 7 and a problem on Arduino DFU peripheral.

What is wrong ?

See "How To Use the Forum".
Meanwhile ALL code and error logs in code tags after Tools/Autoformat for the code.

Hi @solution_maisonneuve.

This "LIBUSB_ERROR_NOT_FOUND" error indicates you have not installed the drivers for the Nano ESP32 board.

When using Arduino IDE, the drivers are installed automatically when you install the "Arduino ESP32 Boards" platform that configures the IDE for use with the Nano ESP32 board, but unfortunately this doesn't happen when you use Arduino Cloud.

The most simple solution will be to install Arduino IDE and the "Arduino ESP32 Boards" platform, making sure to approve the driver installation offer. I'll provide instructions for doing that:

  1. If you don't already have Arduino IDE installed, install it by following the instructions in this tutorial:
    https://docs.arduino.cc/software/ide-v2/tutorials/getting-started/ide-v2-downloading-and-installing/
  2. Start Arduino IDE.
  3. Select Tools > Board > Boards Manager... from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
  4. Scroll down through the list of boards platforms until you see the "Arduino ESP32 Boards" entry.
  5. Click the "INSTALL" button at the bottom of the "Arduino ESP32 Boards" entry.
  6. You should now see a "User Account Control" dialog about dpinst-amd64.exe asking whether you "want to allow this app from an unknown publisher to make changes to your device". Click the "Yes" button in the dialog:

  7. Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

    Successfully installed platform ...

  8. Select File > Quit (or Arduino > Quit Arduino for macOS users) from the Arduino IDE menus.
    All Arduino IDE windows will close.

After you have done that, try using Arduino Cloud Editor to upload the sketch to your Nano ESP32 board again, just as you did before. Hopefully it will be successful this time.

Please let me know if you have any questions or problems while following those instructions.

You are welcome. I'm glad it is working now.
