Composite Devices

Sorry if this Q has been asked before,

What is the correct way to open a reference to a composite device?

If I have (for example) a combined Keyboard/mouse controller it shows up
as 3 seperate devices, the hub (with composite bit set), the Keyboard
Interface (0) and Mouse Interface (1).

Do I open a reference to the hub and then claim an interface or do I
simply open a reference to the interface directly (which shows up in the
device list as a seperate device).

Regards

Shane O'Neill
