START_DEVICE when device isn't present

Hi,
My AddDevice routine is called and
I get an IRP_START_DEVICE sent to
my device even when my adaptor
card isn’t present, is that a normal behavior ?

I your AddDevice routine is called the system thinks
you have a device present. Check the resources you
recieve for the card, and see what the system thinks
it is giving you.

Additionally, folllow the steps for debugging PnP described in:

Have you possibly used the Add Hardware wizard to force installation of
a driver for a device that’s really Plug and Play? If so, you can expect
exactly this behavior. The right way to proceed is to let the system
detect your hardware and then prompt you for the location of the driver.
