    Description

      Right now we have a Python script which is able to discover VE cards using pyudev: https://pyudev.readthedocs.io/en/latest/

      Java does not officially support libudev. There are some projects on Github (example: https://github.com/Zubnix/udev-java-bindings) but they're not available as Maven artifacts.

      However it's not that difficult to create a minimal layer around libudev using JNA. We don't have to wrap every function, we need to call 4-5 methods.
