Unable to upload to STM32 Thing Plus

Have made some progress. I plugged this into a different (non-development) computer and it’s recognized. I had to install ST Cube Programmer IDE of course to get the driver but once I did that it’s working as expected. It’t not a dev computer so I don’t have the Arduino IDE on there - so I haven’t tested the upload yet but I expect that’ll work.

So - given that - any idea where to look to see why the dev computer doesn’t recognize it. I’ve installed the apps as well as the drivers separately and have rebooted, etc.
