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?
