hm ... I am only running Windows 10 Home version 1511, build 10586.494 - BUT my Forerunner 920XT also is not recognised correctly.
I am prompted to format the device which I of course don't want to do at all.
All other USB-devices work correct. Also my GARMIN DriveSmart 50 and the Edge 810 is o.k.
Any idea?
Thank you!
Br, Matthias
