KEA128 Eval-Board in Stand-Alone mode

Our customer wants to use the KEA128 Eval-Board in Stand-Alone Mode only powered with a USB Power Supply.

Their board and Software is working fine as long as they have the KEA128 board connected via USB to a PC.
As soon as they replace the PC with a USB Power Supply the board does not start anymore.

They tried to use the on-board Power Connector, but this fails as their add-on boards connected with the KEA128 draw more current than the on-board SBC can support.

The question now is: How can they get their board starting, using only USB Power Supply?
