OK - seems that error message "The layer is not a valid layer............." is a generic message.

The problem seems to be one of GPSBabel not communicating with the Etrex.

[EMAIL PROTECTED]:~$ gpsbabel -D 9 -i garmin -f /dev/ttyS1 -o gpx -F 
waypoints.out
My eTrex has a USB connection so you probably want:
gpsbabel -w -i garmin -f USB: -o gpx -F waypoints.out

In the QGIS GPS plugin (Device Editor) that would become:
%babel -w -i garmin -f usb: -o gpx -F %out

Hello,

I am relatively new to Quantum GIS, and run Metis under Ubuntu Hardy (amd-64).

Tried to download data from an Etrex GPS and get an error "The layer is not a valid layer and cannot be added to the map". The settings I used are shown in the attached screen shot.

However I reckon I've performed this operation successfully before under an earlier Quantum version.

This seems to be a problem under OSX (http://forum.qgis.org/viewtopic.php?f=2&t=1460) <http://forum.qgis.org/viewtopic.php?f=2&t=1460%29> but I couldn't find any reports for other platforms.

Any advice would be appreciated.

Cheers
Tony
