No ST-LINK detected

[Warhawkquad]

No ST-LINK detected in STM32CubeProgrammer or the IDE. My ST-LINK/V2 ISOL shows up in Windows 11 Device Manger with driver 2.2.0.0 dated 2021-04-01. I thought the version on the ST website was 2.02? I was able to update it's firmware this morning. I downloaded STM32CubeProgrammer 2.17.0 this morning as well. Not sure what to try next to get this working.

Does it work on a Win7 or Win10 box?

Works on Windows 10 just fine. Unfortunately I need it to work on Windows 11.

It works on windows 10 with the same cable.

I only see STM32 STLink under USB devices. No Ports.

Could still be worth trying other cables - could be that Win 11 and/or the PC it's on are just more "finicky"...

That's as expected - the ST-LINK/V2 ISOL doesn't have any VCP.

I've tried cables with no luck. I'm wondering if windows 11 is overrideing the driver installation.

What about the other things - different USB ports (especially if both 2 & 3 available); with/without hub; all other devices disconnected; etc ...

[Warhawkquad]

As it turns out I didn't try all the ports initially. I only tried two. I had to move things to get it to work but trying more ports found one that worked. Thanks!

[Andrew Neil]

Glad that worked.

You'd have thought we'd be beyond that sort of thing by the 3rd decade of the 21st century, but here we are...
