Hello,
I am trying to get this STLink-V3set to connect for an STM32 board that my electronics engineer has designed. Due to being at different locations, I need to get it linked at my location. Several efforts have been made to install the software, install the driver, look at device manager, etc. to no avail
1. The COM light goes on when plugged into the USB on the computer
2. The windows tone is heard when the plug in occurs.
3. The STCube software consistently does not recognize the STLink.
Preliminary questions
1. To get a connection shall I have my board attached to the SWD pins or not, shall it be disconnected from my board?
2. Is power supposed to be lit in the interface box? I only get COM to light up, not PWR
How do I get this connection going?
Below is a photo of my hookup, and a screenshot of the typical response I see from the STCube software.
Thanks!

Doesn't matter, but disconnect the board while debugging.

This is normal if your board is self-powered. The programmer doesn't typically provide power.
Does it show up in Device Manager when connected? Show a screenshot. Should show up as a debug probe and a virtual serial port.
