OK, I think I got it figured out after studying the White Book and a little nudging from you guys.
As Dennis said, hubs are covered under DWTT and are suitable for normal grounding. It does not mention use for compliance with 250.92, however if you look at "related products" in DWTT it refers you to KDER which specifically states that KDER covers compliance to 250.92 for grounding and bonding hubs (which are the hubs with the lug on the lock nut).
So bottom line, if you are going to use a myers type hub in a metallic service raceway it has to be the type with the lug and use a bonding jumper. I my neck of then woods, many seem to think a standard hub without the lug (and jumper) is in compliance with 250.92, but after researching this, this is clearly not the case. Infinity wins.
