WMDC won't detect mobile device

Question

Using Windows 7 Pro. Connect Windows Mobile 6.5 device USB. In Device Manager, I see the device (Microsoft USB Sync) under "Mobile devices" every time I connect the scanner. But WMDC won't connect.

I tried reinstalling WMDC, uninstalling the driver in Device Manager, changing the login for the 2 services, disabling the "Enable advanced network functions" on the device USB to PC setting, rebooting (warm and cold) the device, rebooting the computer. But nothing works. I always see the device in Device Manager, but WMDC never connect.

anyone has an idea what I can try to make it work?? I'm out of idea...

thanks for your time and help
