Sync'ing Visor via usb with Kpilot

Hi, Has anyone had any success sync'ing a Handspring Visor (or any Palm-type device) via usb? I'm running SuSE 8.0 and I can't seem to get pilot-xfer to bind to any of the /dev/usb/ttyUSB* devices - even after updating to version 0.11.3 of the pilot-link utilities. I'd like to sync using Kpilot so that maybe I can synchronise the calendar on my laptop with the calendar on my PDA, but I'm willing to use Jpilot just to have a backup of my data. Thanks, Steve
