SRB_INITIALIZATION_COMPLETE
The class driver sends this request to signal the minidriver that it has completed its initialization.
Comments
Once the minidriver completes this request, the class driver can begin to send SRB_OPEN_STREAM requests.
When this SRB is received by the minidriver, the minidriver should create any necessary Registry entries. For example, a DirectShow filter might register a TV tuner or Crossbar for use with the FilterGraph using the StreamClassRegisterFilterWithNoKSPins routine.
