--- PoE is WAY more expensive that USB power
(USB just does that, and Ethernet, it's an add-on)
--- UPnP required to get even close to USB-like auto-config
(see above about software stack)

Do a whole system design, sell and support a product. Ethernet
is sexy to the programmers, USB is likely cheaper at the bottom-line.
Support costs to explain to customers how to configure Ethernet
alone are crushing.
