What do I have to do to let the USBi Interface being connected to the 1467 ( or 1452 ) via master control port WITHOUT having a PC (Sigmastudio) connected to the USBi when powering the board on ( selfboot )

At the moment I need to disconnect the USBi from the board to succesfully power up the board.

Maybe a physical switch somewhere between the USBi control port connection and the board or a setting somewhere in sigmastudio ?

I found a solutiuon. I soldered a USB socket / plug in the USB cable and connected the +V cable to the DSP board, so the USBi isn't powered by the PC but powered by the DSP Board. So when the PC is disconnected, the USBi is still under power, and the board is still able to power up and selfboot.

Nice solution.
I have mine on a USB hub that is always supplying 5V.
