Problem unable to switch back to USB Native port after using programming port.
I first successfully ran the Python knob.py example. When running the example my computer showed it was using COM port 3
Next Tried running the Arduino knob tutorial. Downloaded the example and Arduino produced this message.
Verify 24584 bytes of flash with checksum.

However, knob would not lit up or change colors. When running the Arduuno knob tutorial The Arduino IDE showed it was sing COM port 5 the programming port.
Next I tried rerunning the Python knob..py example this time Python says
C:\Users\Howard\Documents\Python Test Bed>python knob.py
Traceback (most recent call last):

port = modulo.Port()

File "C:\Python27\lib\site-packages\modulo\connection.py", line 196, in init
raise IOError("Couldn't find a Modulo Controller connected via USB")
IOError: Couldn't find a Modulo Controller connected via USB
Device Manager says Arduino Zero COM5 and the ARduino IDE says COM 5 Native USB port
Shouldn't this be COM3. It appears the Modulo controller is not switching from the programming port to the native USB port.
I tried uninstalling the driver and reinstalling the driver and running the USB Control example. but still got the ": Couldn't find a Modulo Controller connected via USB" error message.
What should I do to get the Modulo controller to run the Python Examples?
