Nano no ports showing in IDE

Development Tools IDE 2.x
1

So I have a Nano clone. When I plug it in I get "USB SERIAL CH340 (COM 7)" on my Windows 10 device manager. But in Arduino IDE (2.0.1) I get "No Ports Discovered" in the add board / port screen. Are there further drivers I need to install for this?

Hi @jameshoyland. If you select File > Quit from the Arduino IDE menus to close all windows and then start Arduino IDE again, does the port still not show up?

Sadly yes, still reports no Ports discovered.

I'm going to ask you to post some additional information that might help us to identify the problem.

Please do this:

  1. Start Windows "File Explorer".
  2. Open the Arduino IDE installation folder.
    (usually C:\Program Files\Arduino IDE or C:\Users\<user name>\AppData\Local\Programs\Arduino IDE).
  3. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
  4. From the context menu, click "Open PowerShell window here".
    PowerShell will now open with the current directory set to the Arduino IDE installation folder.
  5. Type the following command:
    & ".\Arduino IDE"
  6. Press the Enter key.
    Debug output should now be printed to the PowerShell window as the Arduino IDE starts.
  7. Wait for the Arduino IDE to finish starting.
  8. Switch back to the PowerShell window.
  9. Right click on the title bar of the PowerShell window.
    This will open a context menu.
  10. Select Edit > Select All from the context menu.
    This will select all the text in the PowerShell window.
  11. Press Ctrl+C.
    This will copy the contents of the PowerShell window to the clipboard.
  12. Open a forum reply here by clicking the Reply button.
  13. Click the </> 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.
    Code block
  14. Press Ctrl+V.
    This will paste the output into the code block.
  15. Move the cursor outside of the code block markup before you add any additional text to your reply.
  16. Click the Reply button to post the output.

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

So I couldn't follow the instructions but the reason I couldn't solved my problem. I am using a work computer for which I have limited access rights when running as a normal user. When I ran the Arduino IDE with elevated rights it found the COM ports. Thanks for the help!!

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