Like everyone else, I was unable to use my USB connection for my Treo 680 and my Vista 64 laptop. This meant tha my USB sync and charge cable doesn't work, and windows media sync.

I just discovered by accident that if you run PocketTunes on the Treo, it will connect with Windows Media and make a solid connection. Evidently the Pocket Tunes driver allow the oS to recognize the Treo.

That's good for me because I can't use a regular charger for my old a#*! phone and was depending on the power from the USB sync-and-charge.
