I was trying to figure out another problem I ran into while upgrading

involved booting between Ubuntu 20.04 and Ubuntu 22.04 a lot. Sometimes,

I dunno how useful this knowledge is but I learned a few more things.

2. Booting an older OS is not enough to fix the USB Ethernet, it must also be

I tried a few things to try and rule out problems in other places...
1. I inserted a USB stick into the port the USB Ethernet adapter normally
connects to. It shows up on boot.
2. I removed the USB hard disk, since lsusb -t shows it coming off the same
hub. That did not help.

FWIW: The interface is not currently being assigned an address because I
changed /etc/network/interface to make the wifi interface the primary

I tried a few variations on forcibly loading the kernel module (based on
