5V*2A=Max 10 watt. Your usb hub won't work with more than 4 block erupters. Probably max 3 block erupter otherwise you get a lot hardware error. Each block erupter use 2.5 watt at least. And be carefull with cheap adapters. They get really hot and might catch fire, they're not design for block erupters, but for normal use.
