I hope I've found the right place to ask this, please excuse me if this is the wrong forum.

I've been trying to use Google Earth Plus to load my track/waypoints/routes but it doesn't work. I went and downloaded gpsbabel-1.2.8-beta20060219 (on Windows) and ran it through the command line. Here is the output:

$ gpsbabel -D9 -i garmin -f usb: -o gpx -F blah.gpx

It just stay stuck there. (Left is for 20 minutes now).
My GPS is the Garmin GPSmap 76CSx. It is running software version 2.70. I have it connected through the USB, it's the only GPS device connected through USB, and I have been successful at uploading/downloading with Garmin's mapsource and EasyGPS.

Any advice would be appreciated. Thank you,
Jerome
