Traded up from my 300 and just got my 600 yesterday. Went thru all the installs of new palm desktop per intructions. The 600 won't sync (it starts, but never gets past identifying user). Everything else on the 600 seems normal. I know the USB works fine since my old 300 syncs right up with the new software. I've tried the registry cleaner, reinstalling, resetting, changing names, nothing works. Any fine member out there have a solution?
