Hi All,
I am doing a physical read and write operation from a volume filter driver when the volume Is getting removed. but I have observed that my read call was hanging
when I called WdfIoTargetSendReadSynchronously to read when the device is powering down. I am calling this function at WdfPowerDeviceD3Final.
Also what is the diffrence between WdfPowerDeviceD3 and WdfPowerDeviceD3Final ? can I call this at WdfPowerDeviceD3 ?
I appreciate any help in trouble shooting this problem. thanks in advance.
