I've been struggling to connect my nucleo board via ST-Link, I've tried uninstalling everything, reinstalling and my computer still won't detect the board when I plug it in. It's always just COM-3 device or whatever port I use. Tried installing the STSW-LINK009 driver directly from the STM website but still nothing.

Hello @jvu and welcome to the ST Community
Could you please try to connect your MCU to the STM32CubeProgrammer. Don't forget to check that all pins are correctly wired (if it is a Nucleo, ensure that the JP1 is fitted on the USB_STL and that you are connecting the USB cable throw the CN15).
Best Regards.

Thank you for the reply!
I've downloaded the programmer and can connect via J-Link. Is there anything I can do or change to be able to connect to the NUCLEO board with ST-LINK?

Could you share a picture of you're connections (board to PC and ST-link if it is not an eval board). Also, a screenshot of the error that you are receiving will trying to connect to CubeProgrammer with ST-LINK will be really helpful.
Best Regards.

It is connected to CN15

Could you please try using another Cable (USB Data Cable not charging cable).
Best Regards.

I've tried three different cables, which have worked for other boards.

Is this manifesting as a J-LINK or an ST-LINK ?
Trying to understand what you're illustrating with the selective Device Manager image.
I'd agree it's not showing an ST-LINK, so drivers, or cabling, or that the STM32F1 with the ST-LINK firmware has been wiped or corrupted.
Did this work at some point? When did it stop working?
Avoid hubs and docking stations. Try another PC or USB Port.
If you flashed it as a J-LINK, select J-LINK connectivity, not ST-LINK

It's manifesting as a J-LINK. Hasn't worked before.
Is it possible to flash the device again as a ST-LINK?
I apologize for the confusion, I am still new to this.

Ok, but ST-LINK != J-LINK
Pick J-LINK in newer STM32 Cube Programmer, rather than ST-LINK
