Please find the User manual of this board. It has a section about power. Maybe some jumper is missing. These boards have several options for USB power.

As @Pavel A. said, see the User Manual for the board - it will be on the 'Documentation' tab of the Product Page.

The board can't be powered from the user USB connector.
