I have 2 new UNO Wifi rev2 .......Neither of them show up on my COM PORT when i plug them in, instead they show up under "other devices" and my IDE will not communicate with it..

one says "ATm32U4DFU"
the other says "mEDBG CDC"
and they both show up under "other device" instead of COM PORT.....

Yes, I have made an attempt to search this problem but I have not found any answers...

Thanks for any help you may have on this.....

Have you installed Arduino megaAVR Boards in the Arduino IDE? If not, please do that:
  • Tools > Board > Boards Manager
  • Wait for the download to finish.
  • Click on "Arduino megaAVR Boards"
  • Click the "Install" button.
  • Wait for the installation to finish.
  • If you get a dialog asking you to approve the driver installation, confirm.
  • Click the "Close" button.


If you have already installed Arduino megaAVR boards, did you approve the driver installation?

I believe a missing driver is the cause of the "mEDBG CDC". My suspicion about the "ATm32U4DFU"  is that the mEDBG firmware is missing from the ATmega32U4 chip, but maybe it could be a driver problem also.
