My lab partner and I are working on a project for school and we are using an Arduino Mega 2560 for prototyping. The board was working just fine until, out of nowhere, the board was not being recognized at all. I tried reinstalling the IDE but still it does not work. I checked to see if the Arduino driver was installed, but the board does not show up in the device manager. Also, the L LED on the board does not light up at all. Attached are photos to help understand the problem.

grayed out port in the tools drop-down

arduino mega driver does not show up in device manager

If someone could help, it would be much appreciated. Thanks.

  • Have you tried unplugging all the wires from the Arduino (other than USB) to verify it isn't a problem with something in your project shorting out? – Phil C Apr 11 '18 at 2:29

    The board was working just fine until, out of nowhere, the board was not being recognized at all - out of nowhere, huh? What was the last thing you were doing with the board when it was working? – Nick Gammon Apr 11 '18 at 3:38
  • The last thing was upload a simple stepper motor code. – Jérémy Mainguy Apr 13 '18 at 2:42
  • Also, to answer Phil C, nothing is plugged to the arduino. – Jérémy Mainguy Apr 13 '18 at 2:42
  • If you guys have any other tips or tricks or advice in general regarding this issue, anything helps. – Jérémy Mainguy Apr 13 '18 at 2:44
