ST-Link 3V Connection problem with win10 STSW-LINK009 driver

Hello Everyone,

I have issues communicating with my new Nucleo-G431RB using usb driver STSW-LINK009 in win10.  Here is what I found.  After plugging in the use cable to my laptop, I saw an "unknow USB device (Device description request failed)" showed up in the device manager and with an exclamation mark !.  Nothing worked after that.  The driver seemed to be installed correctly, because an "USB Mass Storage Device" showed up when I plugged in Nucleo-F103RB board and communication was working normally.   Is it because the different between ST-Link/V2-1 vs. STLINK-V3 the G431RB had?  It seemed STSW-LINK009 driver worked fine with ST-Link/V2-1 but not STLINK-V3. Is there another driver for STLINK-V3S.  It  appeared the same way on all 3 of my computers with win10. How do I remedy this issue?  Thanks Everyone!

Sounds like a busted board. What's the status of the LD1 LED? Is it drawing excess current? Can you measure voltage rails? 5V_SEL jumper on 5V_STLK?
