A Linux Docker image, probably doesn’t have any USB devices exposed to it-well, it depends on exactly how you run it, but e.g. if you use Docker Desktop for Mac, its embedded Linux VM doesn’t have any USB passthrough support. This is the kind of thing where a physical Linux host (laptop/desktop/NUC/RPi/etc) is much more straightforward than running Linux in a VM (or as a K8S pod in a datacenter somewhere)
