So you are saying that the device actually *does* pop up eventually,
but your systems is simply so awfully slow that the default time-outs
are hit?

If so, you solve this locally for dev-ttyLXU0.device by adding a
JobTimeoutSec= drop-in file (for the [Unit]) section.

Or if you want to increase the time-out globally, consider setting
DefaultTimeoutStartSec= in /etc/systemd/system.conf to any value you
like.
