Run it before and after inserting the Ethernet adapter.

No, that's a "Card Reader Controller".
05e3:0612 Genesys Logic, Inc. is a hub
8087:0a2a Intel Corp. is a "Intel Dual Band Wireless-AC 7265 802.11ac, 2 x 2
Wi-Fi and Bluetooth adapter"

There are no Ethernet controllers in the list. See if unplugging and
re-plugging it produces log messages, and if it does see if they document
anything strange.

You could also try to use the adapter on another machine, or boot the PC
with a different kernel.
