"arduino.enableUSBDetection": true causes Copilot failure to load

[tpak]

Hello,

Unbeleiveable as the title may seem, setting "arduino.enableUSBDetection": true will cause the Copilot extension to throw errors any time VSCode or a project is opened (Shift CMD-N). (Mac, M1, Ventura 13.1 all s/w is up to date - vscode version details at the end of the issue).

Copilot will throw the following message:

output log:

[ERROR] [default] [2023-01-25T21:59:46.291Z] GitHub Copilot could not connect to server. Extension activation failed: "Cannot find module 'file-uri-to-path'

- /Applications/Visual Studio Code.app/Contents/Resources/app/out/bootstrap-fork.js"

Setting "arduino.enableUSBDetection": false will stop the error.

I have also reported this to GitHub support since it is coming from Copilot, but it seems deeply related to this extension and a singular setting, so I am bringing it over here.

Reproducible steps (1... 2... 3...) that cause the issue

• install GitHub Copilot
• install this Arduino extension
• enable Arduino extension setting for USB detection in the user preferences panel, is puts this in settings.json: "arduino.enableUSBDetection": true
• restart VS Code
• the error shown at the top occurs
• change the setting to false and re-launch vs code and the error stops

For deeper troubleshooting purposes, I did a "hard reset/reinstall" of VSCode as follows:

• I completely uninstalled all my extensions
• removed all user data stored in %APPDATA%\Code\User\settings.json
• I turned off settings sync and cleared my data from GitHub/VSCode's cloud
• I uninstalled and re-installed vscode
• I re-installed all my extensions (it threw a few meaningless errors since some were part of packages, but they all re-installed)
• I brought back Copilot settings from settings.json
• I brought back Arduino settings
• the message comes back at this point
• so I narrowed it down, it is one setting in the Arduino extension that blows it all up
• "arduino.enableUSBDetection": true will cause this error with just the simple settings.json file below
• "arduino.enableUSBDetection": false and the error will go away

Removing all extensions except Copilot and this Arduino extension, I can re-produce this each time.

install only two extensions:
code --install-extension vsciot-vscode.vscode-arduino
code --install-extension GitHub.copilot

super simple user preferences json:

{
    "arduino.enableUSBDetection": true,
    "editor.inlineSuggest.enabled": true
}

So, all in all, I can't be sure if this issue is resting on this extension or on Copilot, but I think I have narrowed the scope and it sort of points over here. If support comes back and accepts it as a Copilot bug I will be sure to close this out.

@tpak Thanks for your feedback.

I would suggest you to keep the enableUSBDetection to false as a current solution/workaround. That support is currently broken anyway, so it would be a safe fix for the time being to keep that false. We will work to keep you updated on any future updates to the USBDetection.

Thanks!

@gcampbell-msft, that is what I have done, I didn't realize it was broken, but of course, I only develop for Arduino occasionally. I'll keep an eye out here for updates.
