Managing GPS waypoints on a Garmin Etrex Vista HCx under Linux

I used to use GPSman for uploading waypoints and downloading tracks to/from my Garmin Etrex Legend. When I moved to the Vista HCx I found GPSman didn't play well with the new USB interface. I soon stumbled across QLandkarte, which is a lot more polished (at least GUI-wise) and supports the Vista HCx over USB. It is the best software I have come across for linux interaction with Garmin devices.
