Tell us your hardware? Some commercial board or something you build? Check and test other cables and USB ports. Check wiring. Check your setup.

Hello @johannes-lichtenberger and welcome to the ST Community :smiling_face_with_smiling_eyes:.

I suggest you take a look at this Post. It should be helpful.

I've checked using other USB-Ports, but it didn't help. I'm going to check another USB 3 to USB-C cable, but I doubt, that it helps, either. The board is a new STM32U083C-DK.

Thanks
