Help needed syncing Palm Treo 650 with FreeBSD

[Aniruddha]

I am trying to get my Palm Treo sync with Jpilot. Unfortunately so far 
without results :-( . Who can help me with this? Here's what I tried so far:

Added this line to etc/usbd.conf just above the fallthrough entry:
/
device "Palm"
       devname  "ucom[0-9]*"
       attach "chmod 0666 /dev/ucom* /dev/ttyU* /dev/cuaU*"/

/kldload ucom
kldload uvisor
/
Filled in this 'adress' in jpilot:

//dev/ttyU0/
