The Getting Started Guide v1.0.2 suggests on page 7 under “Connecting the USB interface”, that the board would be supplied with power when connected via the USB connector (J5). However, my board does not turn on (LEDs D9 and D10 are not lighting up) when connected only through USB. Only when I connect an additional 7V power supply to the power jack (J7), does the board turn on (D9 and D10 are lighting up, as well as D6). Only in this state, I also find a FTDI USB Serial Device converter (FT2232H) being connected to my (Linux) PC – when only connected via USB, my computer does not detect such device.
Is this expected? I.e. is the Getting Started Guide wrong about the possibility of supplying power through the USB connector? Or is my board broken?
