ItsyBitsy 32u4 Unknown device

by dempzorz on Sat May 23, 2020 12:58 pm

I have just received my ItsyBitsy 32u4 and I don't believe its working correctly. I'm not able to to see the device under the COM ports, it just shows as unknown device. I've seen in other descriptions to see what the LED is doing, but there are no LED's being lit on the board at any time.

I'm running Windows 10. Any advice?

Thanks

Try this trick and see if helps:

And also see what the red LED does when attempting that.

Thanks, but as noted the LED never comes on the board at all. There is also no way to upload anything since the device never appears as a COM port.

Are there any other suggestions? I don't think my device works.

The only LED on the board is attached to pin 13 of the 32u4 and so must be driven by the 32u4 itself. Until you get software successfully loaded onto the board, there will be no LEDs visible.

Did you try the process linked above?

As stated, I'm not able to upload anything because the device isn't recognized, so there's nothing attached to the COM port.

I've tried anyway hitting the reset button while attempting to upload to nothing, and it doesn't work. The board isn't recognised.

OK. Let's try a replacement and see what happens. Send an email to support@adafruit.com with a link to this thread and your order number and they can send you a new Itsy 32u4.
