We have a driver package that is installed by when our software is
installed. It is installed in to the Driver Store using the
DriverPackagePreinstall function. The drivers are for a USB communication
adapter for an industrial network. Because it is a custom driver class it
can’t be tested by Microsoft’ hardware lab. All the files are digitally
signed and the catalog file is signed as well. In most cases the driver
install fine when the USB adapter is plugged into the system.

We recently found a problem with a system that was taking 10 minutes to
search for the driver. We looked at the setupapi.log file and found that the
system was scanning a DVD we happened to have in the drive. The DVD happened
to have a lot of files as well as 270 INF files on it. I did some research
and found that only the path specified in the
HKLM\Software\Microsoft\Windows\CurrentVersion DevicePath is supposed to be
searched. The only path specified was %SystemRoot%\INF. Our INF file was in
the Windows\INF directory and that was the INF file that was used after the
search.

My question is why does the DVD get searched when it isn’t specified in the
search path? Is there a way to stop it (this doesn’t happen on Vista
systems). Also, the setupapi.log file gives many warnings indicating that the
driver isn’t signed when all files and the catalog file are correctly signed.
Is this a bug that will be fixed or is the fact that the file is signed not
detected for some reason?

See part of the setupapi.log file below.

Thanks,

Not true at all, there is an "Unclassified" suite in DTM that will
allow you to get a WHQL signature for a custom device class.

XP x86 doesn't care about Authenticode signatures at all. For built-
in device classes it will behave as if your driver is totally
unsigned. For custom device classes, I think you might skip a warning
box or two, but you will still see such errors in setupapi.log.

Chris,

Thanks for the quick response. I didn't realize the custom driver could get
a WHQL signature. We may look into that.

Is there any way to prevent the searching of removeable media like the DVD
for INF files when the system is trying to determine the best driver?

my experience with driver install is that windows likes to look everywhere
else first before looking at the infs you provide (I'm assuming that you have
inf for your driver and that it is part of your install package).

Windows usually first looks in infcache file, in windows\inf, and sometimes
entries in this file can lead to your driver not being installed correctly.
When I come across a certain system that has trouble installing my driver,
the first thing I do is delete the infcache (usually named INFCACHE.1). This
normally fixes my problem! On one system I tried everything and my driver
would not install, finally I ran a registry fixup/cleanup tool and this fixed
it - this may also be the answer for the system you mention that always looks
on DVD.

Another common problem you may encounter is when a system contains older
versions of your inf file. In this case windows usually installs your driver
using the existing older versions instead of the current one provided in your
install package.
