IoAttachDeviceToDeviceStack and DO_DEVICE_INITIALIZING

NTDEV
1

Hi,

Can someone explain why does IoAttachDeviceToDeviceStack fail when the
DO_DEVICE_INITIALIZING flag is turned on?

My driver attaches itself to PDOs when their parent bus reports them in the
BusRelations for the first time.

What should a bus filter do if the IoAttachDeviceToDeviceStack fails? What
other opportunity will I have to attach myself?

Is it legal for bus drivers to report PDOs in the BusRelations when the
DO_DEVICE_INITIALIZING is still on?

Thanks

Shahar`

I don’t believe it’s legal for a bus driver to be doing this. Out of
curiosity, what driver are you attaching to here?

The driver that created this specific PDO is usbprint.sys

Are you saying that this is a bug in Microsoft’s code?

Any chance this was fixed in SP2?

Thanks,
