Hi all,
Can anybody tell me what exactly I should do when we receive a
IRP_MN_QUERY_INTERFACE for a Bus Driver ? I am developing a Bus driver with
two child devices , on each child device USB audio device driver ( Microsoft
supplied ) is loaded . In case of windows 2000, I don’t get any
IRP_MN_QUERY_INTERFACE at all, but in case of Windows XP , I receive this
IRP . When I tried to ignore this IRP in child , I received
IRP_MN_REMOVE_DEVICE immediately for that child device . Anybody know why it
is like this ?
Thanks in advance
