Hiding a device from device manager

NTDEV
1

Hi,

I’d like to hide a device rom
the display manager since its
a multifunction PCI device,
theres a need to reveal only one.

I tried to do the following
IoStatus.Information |= PNP_DEVICE_DONT_DISPLAY_IN_UI
in the MJ PNP routine and pass that
IRP down but the device was still showing.

do have any suggestions ?

Thanks, Tom.

Assuming you are talking about doing this in your
IRP_MN_QUERY_PNP_DEVICE_STATE handler, from my experience you have to send
the IRP down the stack first and set PNP_DEVICE_DONT_DISPLAY_IN_UI on the
IRP’s way up.
