Yes, what i wrote here : http://news.lugnet.com/robotics/?n=16569
is what my windoze ;-) system properties tell me.
But things are much clearer now. Thanks to Carsten Mueller !!
The LEGO Camera contains !NO! hub.
The Lego Cam is one device !
To each device belongs one device descriptor.
To each device descriptor belongs at least one configuration descriptor,
which describes the possible configurations of the device.
To each configuration descriptor belongs at least on Interface.
This Interfaces are a kind of subdevice.
So the LEGO Cam has one configuration descriptor and two interfaces (i.e.
the camera and the microphone).
Thank you Carsten, you turned on light in my head. :-)
