@red2blue i use a 13 port usb 2.0 with a 2.5 amp power supply running 11 devices on my pi, so 7 ports with 3 amps is as good as you get, as long as the power supply saying 3 amps isnt a lying pile of junk.
@Nicky ask the seller for support. Why you spent money on free software is beyond me. That seller is illegally selling our work not to mention copyrighted content
