Not detected by USB port - Garmin

Hello


I have a Garmin Forerunner 210 which has been driving me insane. It used to work fine and sync perfectly in the start, however it doesnt anymore.

I am using the Garmin Express program to sync as it is supposted to. However, it cannot detect/add my device. Nor can windows. It doesnt enter Mass storage mode, and disk management doesnt detect it either. However, it just goes into charging mode. Device itself works perfectly and tracks HR/GPS etc., but it is not detected as a storage device by the pc.

Things i've tried.
- Multiple Pcs with the newest Garmin Express (windows 10)
- Reinstall/clean install of Garmin Express.
- Cleaned the watches contacts/connection points etc.
- Reset/hard reset the watch
- Garmins suggestion on forcing software mode on the watch. (Turn it off and hold START/STOP while plugging into USB -> Just goes into charging again)


ANY help is appreciated. Comments, suggestions and certainly solutions

Since it failed on many PC's, probably not the PC itself

• Have you tried different USB 2.0 ports and on different machines. Some devices do better with 2.0 (even tho 3.0 is supposed to be backward compatible)
• Tried a different USB cable?
• Do you know if there's ever (how recent?) there's been a firmware update to your Garmin and can you see what version it runs? (I'd guess the Garmin tool on the PC would manage/report on this if any info to be found). Check with Garmin if more recent? Or if you think problem may have started after an update if you can downgrade the firmware?
