[PD] problem with connecting to Arduino

does "In use" mean that it's the one currently opened by comport, or does
it mean that it's already used by someone else?
here on Linux I'm unable to trigger the "in use" display, whether I open my
device with comport or from another application (but it's not the same
device).
