Can't install kbfiltr.sys

NTDEV
1

Hi,
I’m not sure this happened ever before. At least I didn’t found anything:
I can’t install kbfiltr.sys with the standard kbfiltr.inf!
Yes! The DDK kbfiltr! I modified the kbfiltr driver a little, but did
nothing to the .inf file,

If I install it over the device manager, for the ps/2 keyboard, it tells
me it can’t copy any files which are already there. That seem to be the
files from keyboard.inf which are included in kbfiltr.inf: kbdclass.sys
and i8042.sys. Of course they are already there. And if deleted they get
immediately restored by the Windows File Protection. And I think I
need keyboard.inf. Since it’s a keyboard filter driver. And the
include instruction was always in the .inf file.

How comes this strange error? I mean: on another PC it worked! Also with
Windows File Protection on. The installation worked and I got all the
right registry entries. And since it’s a pnp-device-filter there are
much more entries than just the things under “\Services”. You don’t want
to make them all by hand.

Any ideas why this is happening? What’s wrong with my Windows XP SP2
(all patches included)?

Thanks
Jan Diederich

The INf in this sample does not work out of the box. One clue is that
the HW ID in the INF is bogus

[DDK_Ex.Mfg]
%DDK_Ex% = kbfiltr, *PNP0BAAD

Thanks.

But doesn’t Help.

Yes, the PNP nr. is fake. How “funny” of the microsofties. In the other
files MS did it better and named the entries “PNP0FAKE”. What’s an
invalid hex-nr… And more obvious.
The only things happend:

  • No more warning that this driver may not fit to the hardware.
  • And if there is more than one inf file in the directory, I can only
    choose this, in the install-wizard.

Oh, I read your email address. You are from Microsoft.
Sorry. Don’t want to insult.
But it definitely is irritating. “*PNP0BAAD” “sounds” a little bit
strange. But it’s still a valid hex-number ending. While 0FAKE isn’t.
That’s obvious.

That’s obvious.

On the other hand, PnP IDs are not required to be hex numbers.
*PNP0FAKE is just as valid as *PNP0BAAD.
