My 2014 MacBook Air is running macOS Big Sur 11.6.1. I am trying to use a Lention CB-H23s-0.5M USB A hub. The USB portion of the hub works; the Ethernet adaptor does not.

I tested the Lention hub with my Ubuntu 18 Linux machine and everything worked, proving that the hardware is fully functional.

In ::apple:: > System Report > USB 3.0 Bus > USB2.0 Hub > USB 10/100/1000 LAN, I see that the Ethernet adaptor chip is a Realtek 8153.

How do I get the Ethernet adaptor to work with my Mac?

Merely updating to macOS Big Sur 11.6.2 fixes the problem. No further effort is required.
