One hardware, many functions

Hallo,
I'm developing an USB hardware with two different functions, a custom device and a serial port.
I want to create a driver that shows two devices (so I can use my hardware with my own applications to control custom device, and standard Serial port program for serial port device).

In AddDevice function I tried to call two times
IoCreateDevice, IoAttachDeviceToDeviceStack, IoRegisterDeviceInterface
to create two different devices.
It seems to work and in WinDbg I can see distinct requests for devices I created, but at user level I cannot see two devices.

What should I do to see two different devices in device management tree ?

Thank you very much,
Blu.
