The status lines either say that there's no ethernet link or show the interface as connected and state the link speed. The relevant parts from /var/log/syslog after attaching the adapter without ethernet link read like this: [...] Jun 12 10:48:58 resdz-v13 kernel: [ 4240.398485] usb 2-3: new SuperSpeed Gen 1 USB device number 5 using xhci_hcd Jun 12 10:48:58 resdz-v13 kernel: [ 4240.419463] usb 2-3: New USB device found, idVendor=0bda, idProduct=8156, bcdDevice=30.00 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.419469] usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=6 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.419472] usb 2-3: Product: USB 10/100/1G/2.5G LAN Jun 12 10:48:58 resdz-v13 kernel: [ 4240.419475] usb 2-3: Manufacturer: Realtek Jun 12 10:48:58 resdz-v13 kernel: [ 4240.419477] usb 2-3: SerialNumber: 1 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.447769] cdc_ncm 2-3:2.0: MAC-Address: 00:13:3b:68:00:e9 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.447775] cdc_ncm 2-3:2.0: setting rx_max = 16384 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.447929] cdc_ncm 2-3:2.0: setting tx_max = 16384 Jun 12 10:48:58 resdz-v13 kernel: [ 4240.448901] cdc_ncm 2-3:2.0 usb0: register 'cdc_ncm' at usb-:00:14.0-3, CDC NCM, 00:13:3b:68:00:e9 Jun 12 10:48:58 resdz-v13 NetworkManager[916]: [1560329338.1872] manager: (usb0): new Ethernet device (/org/freedesktop/NetworkManager/Devices/8) Jun 12 10:48:58 resdz-v13 mtp-probe: checking bus 2, device 5: "/sys/devices/pci:00/:00:14.0/usb2/2-3" Jun 12 10:48:58 resdz-v13 mtp-probe: bus: 2, device: 5 was not an MTP device Jun 12 10:48:58 resdz-v13 systemd-udevd[4299]: Using default interface naming scheme 'v240'.
