Unable to upload to STM32 Thing Plus

Thanks. I’m thinking it’s likely not a power or cable issue. When not in boot mode it powers just fine and I’m using the same cable on the other computer. It’s just not recognizing it when in boot mode. So I suspect some sort of OS/driver issue. Maybe uninstalling and reinstalling CubeIDE but that seems unlikely to solve it - especially since I subsequently installed STM32Programmer as well as the driver files standalone.

Very odd problem and I’m still scratching my head on this one. I may have to post this to the ST.com forum as it still seems to be a driver issue.
