That's the mtp-server package's job, right?

I haven't checked yet, but systemd represents all udev devices with a
"systemd" udev tag as a device unit (see man systemd.device and
systemctl). services can then BindsTo= this (like
systemd-rfkill at .service).

If we actually see USB devices in the Ubuntu part, and not just in the
android container, this might even cut out the middle man and get us
one step closer to not depending on Android?  I haven't checked yet
whether we see the device there, though.

Aside from that, I'm sure we'll need the android properties bridge for
other cases still, so many thanks for working on this!

Martin
