STLINK v3SET not recognized by PC

Hi, just bought a STLINK-V3SET to use with EVSPIN32G02Q1S1 evaluation board.

It doesn't seem to be able to connect via USB. I've previously recently used STLINK v2ISOL and it worked as expected, so i already had the driver installed and it should be the same driver.

Tried different cables, different PCs, different USB ports, reinstalling the driver: to no avail.

So what can be the reason here? I'd appreciate any suggestions.

Some additional info:

when i connect the device to the computer, there is no reaction.

No "device connected" sound, no new devices in the device manager.

The LEDs are both on; the red one (COM) is blinking and the green one is continiously one (PWR).
