Debug Mode for FEZ Rhino

Hello All,

I have a FEZ Rhino and I’ve been trying to get it into the Serial Port debug mode but to no avail. I’m trying to get the device to start up as a USB Mass storage device but it keeps throwing the invalid operation exception.

USBC_MassStorage  sdStorage = USBClientController.StandardDevices.StartMassStorage();

NVMD. Was using the wrong pin.
