Topic: Arduino Mega com port not free (Read 566 times) previous topic - next topic


Just got a Mega 2560

If I unplug it, then re plug it, I have to restart the computer before the com port becomes available again.

Most inconvenient


When that has happened to me, I just waited about 15 seconds and then plugged it back in.


The Arduino IDE needs a valid com port. If you restart the Arduino IDE, is it working?

If not, there might be a problem with your system or operating system. Which Windows/Linux/Mac version do you use?


Looks like I was being impatient. Sorry for the false alarm!
