Can’t flash Arduino on WSL2: No device found on ttyACM0

[mferuscomelo]

Hello everyone,

I'd like to upload an Arduino script to my MKR WiFi 1010, but run into the error "No device found on ttyACM0." I'm running VS Code in WSL2 and can view the port under PIO Home > Devices. PIO's serial monitor also works on the port without issue, which I tested after uploading code to my board using the Arduino IDE.

Here's my trace for the verbose upload:

 *  Executing task: platformio run --verbose --target upload --environment mkrwifi1010

 *  The terminal process "platformio 'run', '--verbose', '--target', 'upload', '--environment', 'mkrwifi1010'" terminated with exit code: 1. 
 *  Terminal will be reused by tasks, press any key to close it. 

To be able to develop in WSL, I need to execute the following command in an elevated command prompt: usbipd wsl attach --busid 1-1, which then allows WSL to view the port. Once done, I execute sudo chmod 666 /dev/ttyACM0 on WSL.

Running stty -F /dev/ttyACM0 -a gives me the following output:

What could be preventing the code from being uploaded to the Arduino? Please let me know if you need any more information.

Thanks in advance!
