Thank you for your answer. 
So as I understand a powerful eg. 2.5 A power supply is essential only when 
I want to connect a lot of higher current devices straight to BBB GPIO pins?

Another question that popped to my mind:
I have read 
here https://groups.google.com/forum/#!msg/beagleboard/ka8Nba41YMY/2_QrS9w-A7sJ 
that I may need to disconnect the power line coming from the hub. What if 
the only cable that goes to the board is the USB plug? How do I do it then?
