The HAL stops IO, calls PerformDeviceConfigurationChange() and then restarts IO all in a series on the same thread (actually, from the same function in HAL’s implementation to be precise). So it seems like the only way you could get the behavior you are describing is if your driver returns from PerformDeviceConfigurationChange() before the change has actually completed. Could this be the case here?
