"Not passed Windows Logo testing" warning only on one computer

[Janet]

We were installing the driver for a bluetooth dongle on a few computers and
found that, on one particular computer, the installation produces the
warning
saying "the software you are installing for this hardware has not passed
Windows Logo testing..."

We clicked on "Continue Anyway" and it works fine. However, I'm
wondering why this would happen only on this one computer. All the
computers are Dells, and they are all XP Pro SP2 with all the updates
applied. All the computers have driver signing set to "warn."

Any ideas?

Thanks.

And all of these Dells are identical in each and every respect?

Probably not identical in each and every respect. But should
that make a difference since the identical driver software is being
installed on each machine? In other words, why would one XP
machine claim the software isn't XP logo tested when another
XP machine accepts it as being XP logo tested?

One very plausible explanation is that the driver file is written for a
specific version of the hardware and for which it had been certified. It
is not uncommon for major OEM's to design around specific chipsets but
not necessarily be supplied by the same manufacturer. Take, for instance,
the NVIDIA GeForce 7600 chipset; several video card makers use it. Dell
would not care whose 7600 GT card was used but the driver file written
for one maker would not necessarily pass certification with another but
still work perfectly fine since NVIDIA probably provided the software
to each card maker; NVIDIA might not care whether this software was MS
certified or not.

It's not a really well implemented item. Mostly irrelevant idiot-proofing.
If you know the drivers are the right ones, just ignore the thing. Really
doesn't matter if they really are logo tested or not.

Yes, I'm aware of that. It's just puzzling why it happens.

Do you mean the hardware for which the driver is written? These
"XP Logo" warnings appear before the hardware is even connected
(a USB bluetooth dongle.)

Thanks, but that's not it. The drivers are properly digitally signed
and we don't get any error at all regarding that.

Well, excerpt from that MSKB article:

| When you try to install an update or to install a service pack, you may
| receive an error message that is similar to one of the following:
| ...
| The software you are installing has not passed Windows Logo testing to
| verify its compatibility with Windows XP.

Sounds pretty much like the warning according to your subject line.
