b/c your device was first stopped. i would strongly suggest that you use KMDF and let it implement pnp and power support for you, this is only the tip of the iceburg for the problems that you will deal with

Hi:
On Windows Vista my driver can receive IRP_MN_START_DEVICE 2 times.
The scenario is somehow like the step as below..
DriverEntry
AddDevice
IRP_MN_START_DEVICE
.
.
.
.
IRP_MN_QUERY_STOP
IRP_MN_STOP_DEVICE
IRP_MN_START_DEVICE
Why Pnp Manager send IRP_MN_START_DEVICE twice to my driver?
