Hi Hassan
Thanks for the reply . I am seeing some other Minor function values also.
Like 0xff, 0x1b . I just checked the ntddk.h to see those values have any
meaning. I could not find any . When I checked Irp parameters except the
Minor function values remaining seems to be good . Have any idea what is
going on here ?
Thanks in advance

IRP_MJ_PNP
When I faced the same situation, I found 0x18 corresponds to
IRP_MN_QUERY_LEGACY_BUS_INFORMATION which is not defined in wdm.h but is
defined in ntddk.h.
Eliyas advised that just pass the IRP down if yours is a function or filter
driver or complete without changing the IoStatus if it is a bus driver.
But I had to do
#defined IRP_MN_QUERY_LEGACY_BUS_INFORMATION 0x18 myself since I was not
using ntddk.h
