I just started to use Visual Studio Code with the Platformio extension. Since I am using Archlinux I installed it via flatpack (the oss-version). So for "usual" programming stuff everything works fine but if I try to upload some code to an arduino for example, then this is not possible since platformio does not recognize any ports. Anyway the arduino appears using "lsusb" or "ls /dev/". I already check the documentation of platformio and installed an additional udev-rule but even this does not resolve the platform. The user is also in all relevant groups. So I am a bit helpless how to proceed here. Does anyone of you has an idea? Thank you in advance.
