Fossil Abacus AU5005 Wrist PDA with Palm OS Black
While reviving my long idle Wrist PDA, I ran into HotSync error 6410 – connection lost. Palm’s knowledge base had some suggestions, however, none of their workarounds resolved my problem. Instead, the problem went away by enabling just the “Local USB” connection (and disabling the other “Local”, “Modem”, and “Network” connection types by right clicking on the HotSync menu in the System tray).
