Perhaps it is my turn to be confused by USB port naming and versioning, but looking at the end view photo on Apple's web site and reading the spec description for the adapter I see USB 3 (same rectangular A port as USB 2.0) but not USB C (the rounded next gen physical plug).

Whoops, right you are. That's a USB A port, and a Lightning port next to it. And a Lightning plug on the other end. The Lightning port there is to pass through power while using the adapter.

USB B indeed is normally the old square style plug, or the plug type more commonly found when dealing with mini or micro USB. All tied to the old USB 1 and 2 specs that necessitated a host controller and device arrangement.
