Surface Pro 6, latest Win 10 Home with Updates. Vivosmart HR and Vivosmart 4 activity devices. Plug into the USB socket and I get "Unrecognixed Device" even tho I'm using the Garmin supplied software (same message with TomTom GPS device) BUT, they work just fine on an ASUS Notebook running Win10 - also with the latest updates. Did an online search for alternative drivers without any luck. Can't back out f the updates to see it that is the problem. Suggestions welcomed..
