Hello,
I bought a NUCLEO-H743ZI2 board.
When I plugged it in for the first time, I was able to flash it after two or three attempts (ST-Link was often not recognised).
But now the STM32CubeProgrammer does not recognise the ST-Link at all (I have tried more than 20 times with different USB cables).
When I plug the board into the PC, I get a virtual COM port "STMicroelectronics STLink Virtual COM Port (COM23)" in the device manager.
So the ST-Link seems to communicate. But the programmer still does not recognise it.
What could be the reason?
Solved! Go to Solution.

This is not my Problem.
My problem was that the on-board ST-Link was not recognices.
But I found a solution: This problem only happens if I connect the NUCLEO Board via my USB hub to the Laptop.
If I connect it directly to the Laptop it works fine.

Hubs and Docking Stations have historically been an issue. Gets particularly troublesome with External Loaders, and pushing 8 - 32MB of data, and the connection randomly failing mid process. Issue with board/drivers and ability to recover / retry
