Software: Macintosh OS X 10.3.8 (and at least one earlier version), Palm Desktop 4.2.1.
Hardware: any OS X Macintosh including Pismo, Palm Tungsten T3.

Problem: When I tried to hotsync with USB, I got this error message:

Unknown Sync Error
[16385]

I had just installed the IrDA.prc keyboard driver for my SmartKeyboard SK6688. If it’s active, I get that sync error.

Solution: But all I have to do is uncheck “Active Keyboard” in IrDA on my Palm! Very easy to toggle. Using Bluetooth for sync will also avoid this problem, but since I leave it in the charging cradle at work, I (like to) use the convenient HotSync button.
