This is a good hub that does its job but not totally. I find abnormal end of 2014 there is no at least one port to allow delivering 10W recharging a tablet.
When I plug my iPad, I have this message appears: "No charging in progress". I still recharge but very slow (1% per hour !!).
This comes from a 20W power clearly undersized. It will not connect too hungry watt devices on ports 7 !!
