------------------------------------------------------------
I uploaded the first version of this.
I immediately realized two things:
# {{filter(p -> p.getFileName().startsWith("veslot"))}} - this doesn't work
properly, needs to be changed
# {{assertTrue("Device should not be healthy", device.isHealthy())}} -
incorrect assertion message in line 225

> 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.
