Reply to S4, F1, Midi Fighter Pro USB 2.0 Question

Hey everyone,

I am currently DJing with an S4 and am looking to add an F1 and Midi Fighter Pro in the near future.

The question that I have is: my current laptop has 2 USB 2.0 ports and I would be in need of 3 so naturally I would need a hub. If I were to run my S4 off one port and put a hub on the other one (F1 + Midi Fighter Pro) could I get away with not using a powered hub? Access to power in the booth can be scarce sometimes and I would rather not use a powered USB if possible. Does anyone currently run this setup? Do the F1 and Midi Fighter Pro combined need more than 500 mA?
