Windows 10 won't recognize MKR Zero?

Official Hardware MKR Family MKR Zero
1

Hi all!

I'm trying to get some code onto a MKR Zero. My computer doesn't react when I plug in the board. On the board itself, the green LED is steady on, the yellow LED is slowly (1sec on, 1 sec off) blinking. The IDE can't find the board and my computer doesn't seem to know it's plugged in.

I think I have all the drivers correctly installed, IDE 2.3.2 should be taking care of that. tried it again with an old Uno that I never used, and nothing came up either. What do I need to update?

I gave the installer all the permissions to install, and repeated searching of the forums hasn't yielded any helpful solutions (i tried a bunch of the ones I found, from manually installing teh drivers to unstalling the IDE, nothing helped.)

The only error message the IDE says is "No connection on COM1" and Non-native serial connection.

I'm at a loss for what to do next.

Hi @jmcebula10633. Please try this troubleshooting procedure and then report your results in a reply on this forum thread:

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

  1. Disconnect the USB cable of the Arduino MKR Zero board from your computer.
  2. Open the Windows Device Manager.
  3. Select View > Devices by type from the Device Manager menus.
  4. Open the "View" menu.
  5. If there is a ✓ to the left of the "Show hidden devices" menu item, click on "Show hidden devices" to disable it.
  6. Take note of the contents of the "Other devices" and "Ports (COM & LPT)" sections of the Device Manager tree.
  7. Connect the Arduino MKR Zero board to your computer with a USB cable.
  8. Select Action > Scan for hardware changes" from the Device Manager menus.

Did you see any new device appear in the Device Manager tree after doing this? If so, please tell us where it is located in the tree and what it is named.

You can repeat steps 5-8 multiple times if you are not sure.

Hi ptillisch!

I did it about 10 times, there was no change in "Ports" menu, and my device manager doesn't have a category for "Other Devices".

Update! I tried it on my son's laptop (also Windows 10) and the same thing, doesn't recognize the MKR-Zero or the older Uno.

Make sure the USB cable is completely plugged into both the Arduino board and the PC.

If that doesn't help, you may have a damaged/defective or charge-only USB cable. Try a different cable.

Either of the above can result in the power connections being made (and thus LEDs lit on the board), but no data connections (and thus no port for the board).

I thought it must be something simple I was messing up. Changed to cable and it's there now.

THANK YOU!!!

You are welcome. I'm glad it is working now.

There are MANY usb cables which are made to supply power only. This is a common problem especially if you have a mess of cables in storage like me. Always try a different cable first!
