It seems like you don't really have a good understanding of how your
driver is connected. The port class driver handles all of those ioctls
for you, and turns them into method calls in your driver.
IOCTL_KS_RESET_STATE becomes a call to
IMiniportWaveCyclicStream::SetState, which you are already handling.
How much have you modified the sample code? Is it possible you aren't
returning the IDmaChannel object from NewStream?
