Hi guys! I was using my arduino mega as usual some months ago with no problem. Today i got it again to work on new things and my notebook was not able to recognize it anymore via usb cable! the programm that i wrote before is working properly but my windows is not recognizing it.
I have tried to communicate with another usb cable and with another notebooks and still had the same communication problem. I also tried to press the reset button on the board, but nothing happens! The old programm still there working and i the communication problem was not solved. does someone know who to fix it?
