10:40/05-04-2009 3-day MC50/CRD5000-4000E/U-Connect PPC03 1877210 MC50's in CRD5000-4000E ethernet cradle. Using Activesync or U-connect only allows one device at a time to sync. Can someone explain what is the limiting factor here? Is it Activesync, U-connect or the cradle? Could a third-party syncing software provide simultaneous syncing? What controls or senses the 'connection ended' message and what determines the next slot?
