Sometimes the Windows device manager recognizes the Windows Mobile adapter but Activesync does not recognize the device. In that case, go to Start—>Control Panel—>Network Connections. Look for the Windows Mobile adapter. Right click on it and go to properties. Under “This connection uses the following items” make sure 1) TCP/IP, 2) Client for Microsoft Networks and 3) File and Printer Sharing for Microsoft Networks are selected. If not, just select them and hit OK. Activesync should recognize the device.
