friend, current supplied by usb is in milli amperes which is not sufficient to drive controller applications so either you can use adapter along with 7805 IC or you can buy a power supply unit

yes correct. atleast you have to give 1A current to your supply board so that it work properly.

Better option, purchase power adapter.
