2025-08-25 Dmesg for Cable Matters USB 3.1 to 4 port Gigabit Ethernet Adapter

Picked up an interesting device that integrates a 4 port Gigabit Ethernet adapter that is powered by USB. I decided to plug it into a FreeBSD machine and check its output. The following is the dmesg. Looks like the USB port is also a USB-ethernet (note also the ethernet ports do NOT show up).

ugen0.2: <CMI AX88179> at usbus0

Enjoy!
