### Problem When following the current [installation steps](https://docs.arduino.cc/software/ide-v2/tutorials/getting-started/ide-v2-downloading-and-installing/), the board can't be communicated via the port: `Permission denied on /dev/ttyACM0`. This is because the `idVendor` attribute in the [rules section](https://github.com/arduino/docs-content/blob/2da571564a95fb270c0350793eaea098b2cd2f6a/content/software/ide-v2/tutorials/getting-started/01.ide-v2-downloading-and-installing/ide-v2-downloading-and-installing.md?plain=1#L81) is different (**2341**) from the board's info (**2a03**). Running `lsusb` gives: `Bus 003 Device 009: ID 2a03:0043 ... Arduino Uno Rev3` ### Arduino IDE version 2.3.4 ### Operating system Ubuntu 24.04.01 ### Solution Users should be instructed to check the `idVendor` value by running the above command and adding that to `99-arduino.rules`. OR should add **2a03** instead. E.g., `SUBSYSTEMS=="usb", ATTRS{idVendor}=="2a03", GROUP="plugdev", MODE="0666"`
