Device Profiles
[Real-Time Driver Model]
Collaboration diagram for Device Profiles:

Detailed Description
Device profiles define which operation handlers a driver of a certain class has to implement, which name or protocol it has to register, which IOCTLs it has to provide, and further details. Sub-classes can be defined in order to extend a device profile with more hardware-specific functions.
