I have got Pytrainer working with the Forerunner 305 (including heart rate) on Ubuntu 8.04.
The correct device setting for Garmin Heart Rate is /dev/ttyUSB0
However to get the Forerunner to appear as ttyUSB0 you need to edit /etc/modprobe.d/blacklist. Comment out the line that says 'blacklist garmin_gps' and then reboot.
After that Pytrainer should work with the Forerunner 305, it is a great piece of software.

Does that make any sense in this situation?
