If you try to connect the NetDCU14 as USB-Device with Active Sync or Windows Mobile Device Center without the Explorer to the PC it does not work:
reg del value Launch50 string explorer.exe <= the Explorer ist not active!
You have to modify the registry:
Reg open \drivers\builtin\usbfn
Reg del Value LoadAsyncEvent
Reg save
