@bearer I tried 2 cables with all ports before, but after you suggested it I tried a 3. and it worked. Windows told me installing new device: Duet.
Now I can continue, thanks and sorry for wasting your time for a bit.

@bearer The COM6 does not have any other hardware ids. The Generic USB Hubs have Hardware IDs similar to the ones you featured.

Edit: USB composite devices have these ids as well.

@bearer yes

@bearer Which device?

@bearer Before driver installation it appeared with a yellow triangle. After the installation the device with a yellow triangle disappeared I was not able to find a device which had the driver installed. Screenshot shows current device manager.

Greetings,

I am a beginner so the answer may be something painfully obvious.

I purchased Duet 2 Maestro directly from duet3d a while back. Today I finally got to setting it up. I followed the Guide with the ID: 7, but after I manually installed the driver the device disappeared from Device Manager completely. So I defined a communications port just to check and checked for Windows updates. Nothing helped so I rebooted my computer. That did nothing as well.
This was on a notebook Lenovo G50-30 running windows 10.

After that I connected the Duet board to a 8 year old Windows 7 desktop, but it did not detect the board at all.

When the board is connected to any of these PCs 3 LED turn on. One red next to the connector and a green and a red one on the edge of the board.

Thanks
