STLINK-V3MINIE not detected in debug mode

[vaucher_b]

Hello,

Maybe you can help me, I am not able to start debug session with STLINK-V3MINIE.

Context is: Windows 10 64bit, Intel(R) Core(TM) i5-9400

STMCubeIDE V1.17.0 

Tried with 2 different STLINK-V3MINIE

the STLINK-V3MINIE is seen and updated correctly to V3J15M7 using STLinkUpgrade 3.15.7 tool

When trying to open a debug session, I get the message "No ST-LINK detected! Please connect ST-LINK and restart the debug session"

I tried >20 times, connecting on different USB ports, different USB cables, 2 different STLINK-V3MINIE. I tried to switch OFF the firewall.

When I use my old STLINK-V3MINI it is working fine

When I use a Nucleo board, it is working fine

Any idea what I should do? Thanks

So can Windows itself see the ST-Link? ie, does it appear in Device Manager:

Note the PS there specifically for ST-Link V3

Maybe it's stuck in update mode?

What happens if you try again with the updater?

Thanks for your quick reply

In Device manager, it appears as "ST-Link Debug"- driver date 01.04.2021, version 2.2.0.0

and "Virtual COM Port"

It seems there is no error there.

The update process seems working correctly, I can update again, and I see "Upgrade Successful."

Did you see the note specific to ST-Link V3?

Yes. I think this is not the root cause, because the computer is old (Intel(R) Core(TM) i5-9400) and it is working fine with older STLink such as Nucleo and the old STLINK-V3MINI.

When I open the menu "Run>Debug Configurations" from STM32CubeIDE , tab "Debugger", I can read the debugger S/N (result is 002E00193133510737363734).

I tried with and without USB hub, USB2 and USB3 ports on computer, it's always the same, in device manager it shows the items, in update tool it shows the STLINK-V3MINIE, but debug session always stop with the message "No ST-LINK detected! Please connect ST-LINK and restart the debug session".

Can you explain why the old STLINK-V3 are performing well, but the new STLINK-V3MINIE fail? Is there an important hardware/software difference other than the USB-C socket on the STLINK-V3MINIE and micro-USB on older types?
