increase usb 500ma to 1000a possible?

Hello,

Just to make it clear: If we power the board through eular bus can we supply as much as current we want to usb bus? (of course with the limitations of copper lines).

No. Regardless of the power source (Battery, DC 5V through either micro USB or Euler 2/4), USB ports are always behind the current limiters. 650mA per port.
