I cannot for the life of me get the Arduino software to recognize my Arduino Due. I have installed drivers repeatedly and I have the software on the COM Port the driver is on (COM Port 4).
They can be elusive.
What IDE version?
What computer/ OS version?
Have you tried other arduions, and/ or other computers?
In the IDE, under tools/serial ports, what shows, Is it checked.
Is this your first attempt to load an arduino?
