usb-serial device permission denied

1. What is the sense of commands:

   RUN curl -fsSL https://raw.githubusercontent.com/platformio/platformio-core/develop/platformio/assets/system/99-platformio-udev.rules | sudo tee /etc/udev/rules.d/99-platformio-udev.rules
   RUN service udev restart

   if udev does not support containers and you mount /dev from the parent os or wsl?

Running the postAttachCommand from devcontainer.json...

[55441 ms] Start: Run in container: /bin/sh -c sudo service udev restart
udev does not support containers, not started ... (warning).

2. If idev not working inside container why you install it?

   RUN sudo apt-get -y install --no-install-recommends clang python3-venv udev

3. For my project I use two containers: one for firmware & one for UI.

docker-compose.yml

version: '3'
services:
  firmware:
    build: ./.devcontainer/firmware-container
    volumes:
      - .:/workspace:cached
    command: sleep infinity
    links:
      - frontend
  frontend:
    image: mcr.microsoft.com/devcontainers/typescript-node:1-20-bookworm
    volumes:
      - .:/workspace:cached
    command: sleep infinity

.devcontainer/firmware-container/devcontainer.json

{
    "name": "firmware",
    "dockerComposeFile": ["../../docker-compose.yml"],
    "service": "firmware",

                "ms-python.debugpy"
            ]
        }
    },
    "postAttachCommand": "sudo service udev restart",
    "mounts": [
        "source=/dev/,target=/dev/,type=bind,consistency=consistent"
    ],
    "forwardPorts": [
        8008
    ],
    "privileged": false
}

Hello, sorry for getting back to you so late. I do not have much experience with WSL so I hope someone more qualified can step in eventually. Anyway, I don't really get what you mean with

if udev does not support containers and you mount /dev from the parent os or wsl?

and

If idev not working inside container why you install it?

It seems to me that udev works (on Linux, no idea on WSL, but as stated in the README I only guarantee support for Linux) and that is why I install it.

The only things that seems odd to me is that you set "privileged": false in your devcontainer.json. If you look at the code in this repository you can see that the container runs as privileged https://github.com/prenone/platformio-vscode-devcontainer/blob/f11ca7008793c26b54457225d8a2e4c60008bbb0/.devcontainer/devcontainer.json#L28C1-L30C4.

The code you use seems different from the current one in the repository, can you try to git clone this repo and upload a simple code to your device just to verify? Please reply with the errors you get and I will be more than happy to help you

It works because you use /dev from host system.

I solved the problem as follows:

1. Run wsl --list --all in PowerShell. If docker-desktop is set as default change it to Debian/Ubuntu by wsl --setdefault Debian or wsl --setdefault Ubuntu. If linux distro not installed install it from Microsoft Store.
2. Install usbipd.
3. Run usbipd bind --hardware-id 1a86:55d3 in PowerShell console as Administrator.
4. Run usbipd attach --wsl --auto-attach --hardware-id 1a86:55d3 in PowerShell console as normal user. WSL must be running.

I am currently using my own container based on mcr.microsoft.com/vscode/devcontainers/base:bookworm.

I see... I do not have the time to implement any change nor research it right now. But it seems like you have quite some experience, if you can put together a pull request I can try to test it in the next week and merge😁
