iSync 2.3 Palm Treo 600 No Device Found

I was able to sync my Tro 600 and then it stopped all of the sudden.

Now iSync says no device found and does not recognize my treo 600 when I scan for it. What gives?

Remember, it was working with iCal and Address book and quit....

I have ried reinstalling hotsync and btw: when I enable Palm OS syncing n iSynd it does not place a conduit in hotsync conduit manager.

I call apple care and they couldn't help either....

VERY FRUSTRATING!!!!!!
