Problem with new ST-Link/V2 Programmer

Slh

I have a ST-LINK / V2 programmer that I bought 4 years ago and it works perfect. I recently bought two new programmers but none work with the same connections like old programmer. I updated each firmware but it still doesn't work. Has anything changed in the new programmers? In document of ST-Link i haven't seen any change in hardware. my hardware is as followed:

MCU Programmer

SWDIO (PA13)-> SWDIO (Pin 7)

GND -> GND (Pin 20)

3.3V -> 3.3V (Pin 19)

SWCLK (PA14)-> SWCLK (Pin 9)

Check you have power.

You should also connect the board power back to pin 1 or 2 of the ST-LINK to power the buffers.​

You should tell on what system you work and what exactly does not work?

Thank you! It works, but I'm confuse why my old programmer works without connection to Pin 1 or 2 of programmer. Could it be fake?

Well a lot of the fake/clone devices lacked the buffering that the original design had, so worked due to the more direct mcu-to-mcu connectivity
