Actually I did do my homework. I called the supplier before buying 2 hubs and asked specifically about the output per port and described how I would use the setup. She even emailed me a complete drawing of how to connect the harddrive and the RPi to the same hub and confirmed both should get up to 900mA each. Still have that picture in my email. Then I received the two and one did not work. One of the supplied USB cables was bad. They replaced it and my setup worked for 6 months. I still have one working setup at someone else house. identical to this one. No idea why this specific hub suddenly does not deliver enough power.

I will contact the supplier next week and they'll probably send a new one but I prefer to go for a Belkin one as they are at discount now in a store nearby untill tomorrow.

Blackberry charger output is 700mA, that is the reason I use this one as fast charger for my phone and I also used it to test RPis in the past.
