Does the USB hub I want exist?

I've been googling around fruitlessly for a while, maybe the verge forums can help?

i would like a hub with all of the following attributes:

  • USB 3
  • At least one port capable of charging an iPad at full speed (10W? 12W?)
  • The charging port should also be a data port - none of this charging-only nonsense I'm seeing
  • The charging port always provides full power, no matter what else is drawing power from the hub
  • At least 4 ports total, including the charging port
