I have a few questions regarding the USB port on the later Cambridge 302. The Cambridge manual leaves much to be desired in explaining what it can do.

Is the USB port supposed to supply power to a PDA or other device?

Are you able to transfer files both ways with a PDA or PocketPC (logs and waypoints, etc.) or does the port only work with a laptop?

What is the best way to use both the 303 and a PDA connected to the 302?
