Previously, SetupDiGetINFClassW read INF files with GetPrivateProfileString, which does not substitute %strkey% tokens.
This caused device installation to fail for devices which had driver INF files using %strkey% tokens in Version section.
An example of such device is Vernier LabQuest Mini (08f7:0008) for which Vernier's LoggerPro application includes a driver.
The INF file in question adds a new device setup class and has following entries in Version section:
Class = %ClassName% ClassGuid = %DeviceClassGUID%
Strings section includes following entries:
DeviceClassGUID = "{6B8429BF-10AD-4b66-9FBA-2FE72B891721}" ClassName = "VST_WinUSB"
Previously, when LoggerPro was installed and LabQuest Mini was hotplugged, device installation failed with the following error:
fixme:setupapi:SetupDiGetINFClassW failed to convert "L"%DeviceClassGUID"" into a guid
This caused GUID_NULL to be used and Class was not set to the registry for the device.
With this commit, correct class GUID and names are set to the device registry entry.
