This utility shows noting.
I finally was able to get it working on my PC consistantly, but I don’t know why. I installed the STM32CubeIDE and the STM32Cube Programmer and ever since then I am able to use PlatformIO and ArduinoIDE on my windows10 PC.
Here are the results of the DFU-util -i run show nothing and the Device manager showing com8 and the sucessful Upload to the swan.
The install of the STM32Cube software MUST have Fixed the DFU driver?
My other WIN10 PC still has the same problem. But I cannot install the STMCUBE software on it , because I’ve ran out of disk space
