Hi all
I am confused about how to handle IRP_MN_QUERY_DEVICE_RELATIONS in Lower
filter driver . The lower filter driver pretends as though Class specific
device is present since our hardware is non standard one for USB audio
device . In this case when I get IRP_MN_QUERY_DEVICE_RELATIONS , I am just
passing down the request to next layer in the bottom . I get this request
very often from USB audio drivers very often and worried about how to
satisfy the request in a proper way . Can anybody let me know whether I am
doing correct or wrong ?
TIA
