Can you go through this guide and let us know what you find?

I followed the points one by one.
When I connect the Duet to the PC via USB, only the two LEDs for 3.3V and 5V light up. The status LED remains off as well as all other LEDs.
I can't see a COM port in the device manager. Not even if I swap USB cables, USB ports or computers, even if I use a USB hub.
Also after performing the "Fall-back procedure #2" no COM port appears. -
Have you loaded the Bossa software yet? Does a port become selectable there?
-
Yes, I've tried the Bossa software, but that doesn't show the connection either.
-
And the reset jumper has been applied and then removed?

@jay_s_uk said in Duet3D USB connection is not working:
@phaedrux @Marethyu bossa doesn't work with a duet 3 mini 5+. you need to double tap the reset button to make a USB drive appear. then drag the .uf2 file over, which will cause it to reboot
Thanks for the catch!
-
The Duet 3 mini 5+ has no reset jumper only a reset button.
I also tried double tapping the reset button, but this didn't change anything and COM-port is still not showing up. -
@marethyu it doesn't show as a com port, it shows as a folder, like a usb drive
-
@marethyu for manual Mini 5+ firmware update, see https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#duet-3-mini-5-wifiethernet

@jay_s_uk no matter what I do, neither a COM port nor a folder is displayed.
The only two things that work reliably are the 5V and 3.3V LEDs.@droftarts I've already read that, but it can't be executed because I can't get a working connection to the board.
-
@marethyu Is there any way you can confirm that your USB leads are definitely data leads? Many USB leads sold are power only. Is there any damage to the USB port on the Duet?
It is strange that the STATUS LED is off, not flashing or pulsing. If you double click the reset button does it pulse from bright to dim and back again, even though it doesn't show up on the desktop?

As I wrote before I tried different ports, cables and computers without any effect.
The USB cable I use now was previously used for data transfer and it worked perfectly. So I'm sure it's a USB data cable.I can't see any damage to the Duet's micro USB port. I also compared the USB port of the Duet with the micro USB port of a Raspberry pi, but can't find any differences.
The STATUS LED does not light up, blink or pulse when I connect the board to the computer. When I double tap the reset button nothing happens.

@marethyu Okay, I think we need to replace the board under warranty. How long ago did you purchase the board from RatRig?

I bought the board in February 2022.
