Upload fails: "No DFU capable USB device available"

Development Tools Uploading

For me, on a new device it gives a message:
Warning: Invalid DFU suffix signature
A valid DFU suffix will be required in a future dfu-util release
No DFU capable USB device available
Failed uploading: uploading error: exit status 74

Hi @liyapets. I'm going to ask you to provide the full verbose output from an upload attempt.

:red_exclamation_mark: This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

  1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
    The "Preferences" dialog will open.
  2. Uncheck the box next to Show verbose output during: ☑ compile in the "Preferences" dialog.
  3. Check the box next to Show verbose output during: ☐ upload.
  4. Click the "OK" button.
    The "Preferences" dialog will close.
  5. Attempt an upload, as you did before.
  6. Wait for the upload to fail.
  7. You will see an "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
  8. Open a forum reply here by clicking the "Reply" button.
  9. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.

  10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the error output from the upload into the code block.
  11. Move the cursor outside of the code block markup before you add any additional text to your reply.
  12. Click the "Reply" button to post the output.

The above text is a detailed description of the problem. I checked the Com port and it turned out that the Arduino IDE provides connectivity to the Arduino_Giga R1 WI-FI via Com port 8, and not via Com port 13, which is connected to the Arduino_Giga R1 WI-FI in the PC device manager. I set the Arduino IDE to connect via com port 13 and everything went smoothly.

Thanks for taking the time to post an update with your solution. I'm glad it is working now.
