If anyone is still having problems seeing a USB to Ethernet connection in Network settings, here's what worked for me.
The package provides the installation files for ASIX AX88772 USB2.0 to Fast Ethernet Adapter Driver version 3.18.2.0. If the driver is already installed on your system, updating. This is the driver for the AX88772 USB2.0 to 10/100M Fast Ethernet Controller with Embedded PHY. AX88772 is a high performance ASIC with embedded 28KB SRAM for.

1. I'm using the Apple dongle, USB to Ethernet. OS is High Sierra 13.13.4
2. Could not see the connection in network settings.
3. When you plug in the dongle, go to the menu bar, and click on About this Mac. Choose System Report. Scroll down to the USB section. You should see AX88772 (it's important that the dongle is plugged into the USB port on the MB). I think that's what the dongle wants in terms of the driver, which for some reason seems to have been broken in this iteration of OS.
4. Go to the ASIX website and download the driver for AX88772. I used the latest version 2.6.0
5. Install the package. The machine may give you a message saying your security preferences are blocking it. Just go to security preferences and tell it to allow installation.
6. The machine will ask to restart. Restart it.
7. Go to network settings. You should now see the option for the USB to Ethernet connection. Connect your Ethernet cable to the dongle, and you should be in business.
Hope this helps. Just wasted 5 hours of my life over a few days trying to figure this out, and add in two hours with the ever polite, but in this case unhelpful Apple support people.

I read the thread on buying a dongle and connecting the ethernet to the TV's USB via a Belkin dongle:viewtopic.php?p=455800
The dongle that RokuShawn recommends has been discontinued for a new product here:

I bought this new dongle and hooked up to my Sharp 43 inch Roku TV.
I've done the system restart, the factory reset, and the reboot to no avail.

I called Sharp and they say this will not work, that there's no way to get drivers into the TV, but isn't the belkin dongle 'driverless'?Insignia Usb To Ethernet Adapter Ax88772 For Mac Free
