You just need to return and wait until your Process callback gets tickled
The problem is I *always* get NULL. Actually, if I don’t specify
KSPIN_FLAG_ASYNCHRONOUS_PROCESSINGin the pin descriptor, the Process
callback is called over and over again from ks!CKsQueue::SetDeviceState.
Do you return STATUS_PENDING or STATUS_SUCCESS from your Process
callback? Has the graph changes to KSSTATE_RUN, or are you still in
KSSTATE_PAUSE? Do you set KSPIN_FLAG_PROCESS_IN_RUN_STATE_ONLY?
