1394 inf for multiple instance id

NTDEV
1

Hi folks,

I am witting a WDM driver for a 1394 based device.
I have a problem with the inf file for installation. Every time I
insert a new device with the same Hardware Id but different (unique)
chip id (from 64 bit identifier), the Win2k /XP new hardware found
wizard pops up. I do not understand when the hardware Id is same (of the
form XXXX&YYYYYY) then why shouldn’t the device manager install the
driver on its own? It installs the new device from the same inf only
after manual intervention. Are there any specific entries in the inf
file for this? I have tried adding ExcludeFromSelect directive but it
doesn’t seem to help.

Any suggestions will be highly appreciated.

Thanks,
Hemant

You need to get your driver package signed. Then the install will be
automatic.

I have tried
My Computer -> Properties -> Hardware -> Driver Signing
and selected Ignore option, but it still asks for the driver.
Is it that Microsoft has put that dialog box just for GUI sake and it
does not act upon it irrespective of the option selected by the user?

Or is there any specific entry in the inf file that needs to be present
to stop the pop up box from showing up?

Thanks,

The Driver Signing -> Ignore option simply prevents the annoying “STOP!
This driver is unsigned and installing it will probably result in
sterility and the end of the world as we know it” dialog. It does not
make unsigned drivers act as though they were signed. In particular, it
does not affect the decision on whether or not to request a new driver.
