the reason behind 2 plugs for each device is because they are drawing more than the 500ma each usb port can provide so you will need to go with 7 port hub and maybe only give it 2 amp power and hope your other devices only draw minimal power hope that helps SNO
Most devices though that have high power draw have their own external power abilities. Also when a 7 port hub supports only 2 amps, dont you also have to count the power draw from the main data port? So in saying that, more then 2 amps is techinically going to the hub.
