CF cards for my camera have USB built in; that simply would not happen if ethernet was used. At the time, the 1.2mbps interface was available on 8051 silicon for free. USB could address many devices through very low cost hubs, at a time when ethernet hubs were very costly. Now, USB 2.0 offers 480mbps from $20 host controllers. How much for the equivalent gigabit ethernet interface and switch? You might regard it as a train wreck, but the technical requirement and demand was and still is there.
