Section 2: Understanding Your Phone2R: Troubleshooting 169Common ProblemsThis guide contains common solutions to problems that may arise whenoperating your i500. Please look over the following list of solutions beforecalling PCS Customer Solutions.HotSyncQuestion: I occasionally see an error message when HotSync starts upthat says that Com port X is not available or the Com port setting changeswhen I plug the i500's USB port into my system.Answer: There are additional USB drivers that were installed when youwent through the setup from the i500 distribution CD for the SamsungUSB Composite Device and the Samsung CDMA modem. These driversare not actually used during HotSync operations. As with all USB TAPICom port drivers, the Com number being used will change if you plugthe cable into a different physical USB port on many systems and laptops.Additionally, if you have other Palm OS® serial devices, or Palm OSdevices with USB-to-Serial converters like the Samsung SPH-i500 or thePalm TM USB Connect device, you must maintain Local Serial checkedin order to sync these devices. The i500 is a native mode USB device; youMUST have Local USB checked to avoid problems during HotSyncoperations. We recommend that you leave the Local Serial entryUNCHECKED, unless you are actively syncing one of your other devices. Ifyou see any error messages regarding Com port availability fromHotSync, just hit the OK button. As long as the Local USB setting ischecked, you will HotSync without problem.Question: Can I HotSync numerous devices to one user?Answer: You should not synchronize multiple devices unless they arethe exact same hardware device. (This is especially true with PDA/Cellular handset hybrids.) The best way would be to beam your AddressBook, Memo Pad, Todo lists, etc from the old handset to the i500. Installthe Palm OS applications one at a time. That way, if there is a problem, itcan be narrowed down quickly to the correct device or profile.
