True that, George. I was just surprised, as I had a few different USB-to-Ethernet adapters provided to me at work and none of those would work, and many Google searches solidified the suggestion that there were only a few USB Ethernet chipsets (chip manufacturers, chip-somethings, whatever) which were supported by PXE.
The search was made more difficult in that even in the last few years (2016-present) people seem to continue to prefer Legacy booting over UEFI. If I ever decide to get the other device, I’ll let you know how it works so it can also be added to the list, if that’s something you guys are keeping up.
