This GUID is used by toaster bus driver to created its device interface. Why do you think you should use it in your filter driver? It should be unique to every different driver.

Hi Don,
My filter is based on the Toaster sample.
This sample uses the file public.h which contains the following defintion:
DEFINE_GUID (GUID_DEVINTERFACE_BUSENUM_TOASTER,
0xD35F7840, 0x6A0C, 0x11d2, 0xB8, 0x41, 0x00, 0xC0, 0x4F, 0xAD,
0x51, 0x71);
The Toaster bus (and filter) uses the same public.h
In my case the bus is a Microsoft driver for which I do not have sources.
I have to write a filter for Microsoft’s bus driver.
I think I must use the same DEFINE_GUID as used in Microsoft’s bus driver.
How can I obtain this DEFINE_GUID ?
Thanks,
Zvika

What are you really looking for? There is no “GUID of driver”. There are:
- Device class GUID’s
- Device interface GUID’s
- GUID’s used as part of some device ID’s
- GUID’s used for other purposes
So what are you really trying to do? You talk about a filter driver, is
this a device filter, if so use the device ID, or a device class filter then
use the device class GUID, either of those you can get from the device
manager.

Subject: [ntdev] Obtain GUID of driver supplied by microsoft
Hello,
I have to write a filter driver for " Intel R ICH10 LPC Interface
Controller" supplied by Microsoft.
For this purpose I need the GUID of the existing driver.
I used the following procedure:
Control Panel > Device Manager > Right Click on Device > Properties >
Details Tab > Change ‘Property’ to Driver Key >
and got the following data:
{4d36e97d-e325-11ce-bfc1-08002be10318}\0038
"{4d36e97d-e325-11ce-bfc1-08002be10318} is the class GUID contained in the
inf file (machine.inf)
This is not what I need.
In the sample filter.inx, the device id is:
{b85b7c50-6a01-11d2-b841-00c04fad5171}\MsToaster
But in public.h used by the bus and filter the define is:
DEFINE_GUID (GUID_DEVINTERFACE_BUSENUM_TOASTER,
0xD35F7840, 0x6A0C, 0x11d2, 0xB8, 0x41, 0x00, 0xC0, 0x4F, 0xAD,
0x51, 0x71);
Can you help ?
Thanks,
Zvika
