The issue I had was related to the fact that the dynamically created dev files (ttyUSB0 and ttyUSB1) didn't have sufficient permissions. When I had my pilot program open, I pressed HotSync, followed by a chmod 777 of ttyUSB* and voila, it was working. Of course, this is a hack. A long term, proper, solution could be found in these URLs (provided by Craig White on this list):

Not necessary for this but if you want a lot more info on usb/udev etc... http://www.reactivated.net/udevrules.php
Hope this helps,

A better approach IMHO is the one given in the second link http://www.reactivated.net/udevrules.php where there is a list of examples and one of them explains how to configure Palm Devices. This one does not make the device world writable but makes you the owner of it.
