Forerunner 305 won't sync

I'm trying to upgrade from the Garmin Communicator Plugin (which seems to no longer work with Chrome) to Garmin Express. My device is recognised, but never syncs. I have attached a portion of the log file to this post - the error seems to be as follows:

18:25:39.0371 | 9 | I | GarminModeUsbDeviceReader for \\?\usb#vid_091e&pid_0003#5&2107f3b7&0&2#{2c9c45c2-8e7d-4c08-a12d-816bbae722c0}

Any advice much appreciated,

  • Chrome has withdrawn support for plug ins, other browsers will follow as plug ins are being phased out. IE, Safari and Firefox still support it at the moment. Check here for exact details:

    Just click on downloads and compatibility

    Unfortunately the Garmin Communicator Plugin doesn't recognise my device in either Firefox or IE either. It seems like Garmin Express is the way to go, but that doesn't work for the reasons in my original post :-(

    Hmm, so I uninstalled everything Garmin related, rebooted, installed the USB drivers and Garmin Express (clicking yes to sharing anonymous data this time) and it seems to be working. Hmm!
