Hi
I have a signed driver (the .sys files are digital signed and it is WHQL signed)
for some reason the driver version is missing from Microsoft WMI class “Win32_PnPSignedDriver”.
I have the version in INF and also in the resource file in my driver.
In device manager I see the version in the driver properties and in driver details.
any idea what can cause this?
from where the WMI takes this information?
What sort of driver is this?
For NDIS, WMI and NDIS OID handling are related. If the NDIS driver does not
support the correct OID, then the WMI call can’t fetch it.
Don’t know how WMI maps to other driver types…

it is a Generic Driver (Function Driver, in System Class)
Have you tried driverquery /SI ? Does it display your driver?

“driverquery /SI” display my driver, this is the output line of mydriver:
“MyDriver N/A FALSE MyCompany”
When I look in the device properties (and the same in Driver File Details Windows) in the device manager I’m seeing:
Digital Signer:
“Microsoft Windows Hardware Compatibility Publisher”
ideas any one?

An idea: the .sys file is signed, but the whole package (INF) is not. Someone has tampered with the .inf or other file?

I double check the my CAT file. it is valid.
correct my if I’m wrong on Device Proprieties in Device Manager I got:
Digital Signer: “Microsoft Windows Hardware Compatibility Publisher”
if the CAT/INF file was not valid, I wouldn’t see that, right?

No… it just says who signed the cat (which contains hashes of other files
listed in the inf).
I am not sure that the dev. manager property page goes and scans all these
files.
