Arduino UNO WiFi Rev2 installation help

Official Hardware Classic UNO WiFi Rev2
1

I installed the Arduino WiFi Rev2 board and selected it. I installed The arduino mega avr board package.

The board still does not show up as a COM device. It shows up in Win 10 device manager as "PORT USB Serial Device""
I am using Windows 10 and Arduino 1.8.9

What else needs to happen to make it recognizable as a Com device?

If you unplug the Uno WiFi Rev2 from your computer, does that device disappear from Device Manager?

3

Yes it does. I also tried to remove the device AND the driver. Then I reinstalled the the Arduino Mega AVR and got the same result.

This is very strange. If the driver wasn't installed (which should have happened automatically during the Arduino megaAVR Boards installation in Boards Manager), the board should show up in Device Manager as something like "mEDBG CDC", not USB Serial Device. Is this an official Arduino Uno WiFi Rev2?

Please do this:

  • In Device Manager, double click on "USB Serial Device".
  • Click the "Details" tab.
  • From the "Property" dropdown, select "Hardware ids".
  • Post what you see in the "Value" window here.

USB\VID_03EB&PID_2145&REV_1000&MI_01
USB\VID_03EB&PID_2145&MI_01

I went to the Mega AVR folder and installed the driver again. Now it shows this in device manager.
mEDBG Virtual COM Port.

Still no Com1,2 etc.

The VID/PID is correct.

I was going to suggest you install the driver as the next step, but you're ahead of me! My Uno WiFi Rev2 also shows as mEDBG Virtual COM Port in Device Manager, but mine was assigned a COM port.

Try restarting your computer just in case that might fix the problem.

I want to be certain we are talking about the same thing here. In the attached photos, you can see the device manager advanced settings on the board does show a com port, but in the second image, you can see that the Arduino IDE does not see a com port. That is the port I am talking about when I say there is no available com port assigned to the board.

And yes, I have since rebooted the PC.

Yes, I do understand. This is how the Uno WiFi Rev2 looks in my Device Manager tree:

You can see that Windows assigned it to COM30 on my computer, but it doesn't seem that it was assigned any port number on your computer for some reason.

I wonder if I am missing some Virtual Port Driver?

I have done everything I can think of to make this work, with no success. I may be looking at a compatibility problem between my hardware and the UNO WiFi Rev2. My hardware is an iMac running Windows 10. It has been compatible with all software and hardware I have used in the past year and a half, but that doesn't mean it can't be the problem here.

If someone else has a MAC running Windows 10 and has the Arduino UNO WiFI Rev2 working with it, please let me know.

Thanks.

I tried this UNO WiFi Rev2 on a Windows PC and it works just fine, that's proof the board is okay. One the iMac running Win 10 I uninstalled everything arduino and did a clean install of 1.8.9 and the Mega AVR and the original problem still exists.

I am going to open an issue on this and hope the developers agree this is a bug. The iMac running Win 10 is my main PC and I would hate to have to use something else just for this particular board. I have successfully run several other boards on this configuration:
arduino UNO
arduino Leonardo
NodeMCU ESP8266

Those all work just fine.

And thank you Pert for trying to help.
