Hi,
to output data on the native USB port you need only to write SerialUSB instead of Serial.
In my project I need both ports, Serial and SerialUSB. Every time when the sketch shall be compiled I have to unplug the cable to the native USB port and when verification is running plug it back again. Otherwise upload of the program is not possible.
Is there a way to avoid all this unplugging and plugging?
(I use Win10, 64 bit)
