Just as an example of something remotely like what you might expect to see in the dmesg output, here's what I see when I plug a usb-ethernet adapter into a Ubuntu 16.04 USB 3 port:
[...] [2793539.351788] usb 3-2: new SuperSpeed USB device number 2 using xhci_hcd [2793539.378837] usb 3-2: New USB device found, idVendor=0b95, idProduct=1790 [2793539.378846] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [2793539.378851] usb 3-2: Product: AX88179 [2793539.378856] usb 3-2: Manufacturer: ASIX Elec.

Note, in my case I see the ethernet interface is named eth0. Your mileage may vary.
