Topic: 3 powered USB devices

Hi all,

I am just about to purchase NI Maschine to complete my setup. ie.

RME Babyface
Novation 49SL MKII
NI Maschine

Now, my simple question is, seeing as all three are USB powered. Will they all be fine connected to my 27" iMac i7 at the same time?

I'm sure they will and the iMac will have no issues powering all three, just would like some feedback on this to put my mind at peace yikes)

Many thanks.
