48 Synchronizing Information With Your Computer
Sync connection problem
The desktop Microsoft ActiveSync 4.0 and later versions utilize a network type of connection with Windows
Mobile powered devices, since this allows faster data transfer than a serial USB connection. When the PC is
connected to the Internet or a local network, in some cases, the PC may disconnect the connection with your
device in favor of the Internet or network connection.
If this happens, tap Start > Settings > Connections tab > USB to PC, then clear the Enable advanced
network functionality check box. This makes your PC utilize a serial USB connection with your device.
The USB to PC ( ) icon appears on the Today Screen when serial USB connection is used.
