Cool

Hmm, true. I wonder if the ExecStop line is really necessary, as it
doesn't make sense to execute this after the device is plugged out. So
if you drop this, you can drop the RemainAfterExit as well and it
should work for subsequent insertions.

Another way that comes to mind might be to add
ENV{SYSTEMD_ALIAS}="/$name" to the udev rule and add
"BindTo=%i.device" in the unit section of the service file.
