Since you have the port already open in  5, scanForArduinos isn't going to
check that port.
If you clear that Arduino variable , or restart octave, and then call
scanForArduinos, it should show it. 

After programming the Arduino you don't need to reopen the Arduino ide,
unless you want to program it again
