I figured it out eventually too. If you agree that the documentation is lacking and there's a number of people reporting on this problem the bug is there. Did you create one to follow up? Otherwise I think this one should remain open.
What worked for me in the end with the Treo 600 was to use KPilot and set "usb:" as Pilot device under General Setup -> Device.
Felipe,
