ST-Link connection problems plaguing project progress

[LysAn]

Hello,

we have purchased multiple Nucleo H723ZG and H7A3ZI-Q. Since the beginning, connection problems with ST-Link are plaguing the project. It is impossible to reliably debug, because connection with the host can't be established via USB. We have checked all possible sources (like different computers, cables, docks, ports, software, et.c.), but the issue sporadically appears, even with brand new boards out of the box, which costs money.  Other users face similar issues and I wonder what steps ST wants to take.

Best regards

Hi all, attached are two images showing what happens when I connect my STM32 board to a MacBook. The current draw is different what puzzles me. Once the Current Required is shown, once not.
