I'm not replugging mine, but as I noted, the Thunderbolt service (I forgot it's
bolt.service , not thunderbolt.service) is producing a similar effect. I do
indeed see similar messages to yours *after* bolt.service starts:

Aug 26 11:47:21 xps13a.happyassassin.net systemd[1]: Started bolt.service -
Thunderbolt system service.
