I have umdf2 virtual serial driver. Application connect to it and when application is closed the driver function EvtDeviceAdd is being called again creating new queue and everything. This is happening ONLY when i have added below code and accepted Open request in EvtFileCreate.
WdfDeviceInitSetFileObjectConfig(DeviceInit, &FileObjectConfig, &DeviceAttributes);
May i know what is the reason behind this?
My aim with above code snippet was to get notified when Application open serial device.
I want to get notified up on Device open by application, but not EvtDeviceAdd is being called(second call to EvtDeviceAdd reset by underlying communication channel)
Any help would be really appreciated.
