USB cable troubleshooting:

• Check that the USB cable is plugged directly into the computer rather than through a hub.
• Restart the computer, without disconnecting the USB cable or turning off the phone.
• Check that the drivers are installed:
  1. On the computer: select Start > Control Panel.
  2. Select System > Hardware > Device Manager.
  3. If installed correctly, in Ports (COM & LPT) you will see Sony Ericsson XXX (COM?) and Sony Ericsson YYY (COM?).
  4. If not installed, right click on the entry in Other Devices and select Update Drivers and complete the Hardware Update Wizard.
     Note: If your phone supports PC Suite or Active Sync, the drivers are included in the application.
• Remove software for other phones and PDAs, and then uninstall and reinstall the drivers. If McAfee software is used, the Sony Ericsson software should be reinstalled with this temporarily disabled. In some cases it has to be uninstalled to allow the connection.
• Run a spyware scan.
• Try connecting the phone to another computer to help diagnose the problem further.
