Where are device interface class guids defined?

NTDEV
1

I’m trying to describe to a guy how to use the SetupDi functions to
enumerate the scsi devices on the system, and I can’t for the life of me
find the header file where the device interface class guids are defined. It
isn’t in setupapi.h.

Anyone know?

Thanks,
Loren

Loren,
Device interfaces are defined all over the DDK… just run a search for
“GUID_DEVINTERFACE”. Storage relaed device interfaces are probably in
ntddstor.h.

Well it depends on which interfaces you want to enumerate. Ntddstor.h and
ntddscsi.h and winioctl.h all have device interface guid definitions for
‘things you might find on a scsi bus’.

In this case the required guid was ‘scsi bus’ itself. I think I found it in
ntddscsi.h; I forget now.

The box being searched for is a hard-disk audio playback device that claims
it is a Processor device class. The programs that play with it search all
the scsi busses doing the necessary inquiries looking for the id string,
then let the user pick which device to control if multiple are found. They
beat on it in raw device mode, since it has an ecclectic command set (and
implementation).
