Is this a genuine ST-Link?

Originally a comment on the How to recognize a genuine ST-LINK/V2 versus a cloned one Knowledge Base article.

Moved to main forum for better visibility / discussion.

I bought this  ST-LINK V2 on Amazon ( see pictures) . I don't think its' a genuine STM device. STM32CubeIDE and STM32CubeProgrammer recognize it but No STM32 target is found ( STM32L051K8U6)

I notice that my ST-Link V2 does not provide clock signal on pin 9 (SWCLK) 

I'm using VT ref pin, SWDIO pin, SWDCLK pin, GND pin and RST pin.

According the pictures you shared especially this one:

that's not a genuine ST-LINK but it's a copy of it.

The genuine one has this look and feel:

Amazon is not an ST Distributor - so that alone almost certainly means it's a fake.

You can find official ST Distributors here:

Questions about authenticity and signals really show how trust is built through clear verification, similar to how Marathi birthday culture values sincerity over show.
I recently adapted a traditional blessing for a family birthday and it felt sincere; the takeaway is to verify fundamentals step by step, because like happy birthday wishes in marathi, authenticity is felt when the basics are done right.
