Tried searching in digikey, it always come up with the RJ-45 with USB type connectors. :x
Edit:
Can you just bend the 4 tabs and peel back the solder mask a bit and then solder it over the board (Toplayer)?
The land pattern doesn't fit either. Most of the ones I've seen had the tabs in the middle of the double rows. Doing a look at images.google.com didn't reveal anything either.
It really doesn't matter, I got a replacement hub for pennies. Nearly all of the possibilities I found had 4 tabs.
Connectors often have annoying differences like this to avoid copy infringements for the shield.
But a 4 tab inset makes most sense for mass soldering and mechanical alignment. (did U try AUK?) nevermind 500pc min.
