I have just bought one arduino due from Amazon.
I successfully programmed the due with simple codes such as binking LED etc. I was using Programming port at that time.
Now I want to see the Due's performance with Native port. I tried programming the Native port but as soon as the sketch gets uploaded the COM port of my due changes. IDE does not even recognize that it is Due's Native port as it is not mentioned under the ports tab of tools. (Before uploading the sketch, it was mentioned)
Also even if I use SeriaUSB class, I can not see anything printing on the serial monitor.
What seems to be the problem??
