PRB: OSR2 Device Installer Requires Matching Hardware IDs


The information in this article applies to:

  • Microsoft Win32 Device Driver Kit (DDK) Windows 95


A hardware device inf file that installs correctly under Windows 95 (as well as OSR1) may not install correctly under OSR2. The OSR2 device installer creates a dialog box saying that the inf does not contain information about the device.


The OSR2 device installer requires a match between the hardware ID in the inf file and the actual physical hardware ID created when the device is enumerated. Versions of Windows 95 prior to OSR2 did not require that the inf hardware ID match the physical hardware ID.


To find the correct value to use for the inf hardware ID, you can copy the device's physical hardware ID found in the HKEY_LOCAL_MACHINE\Enum branch of the registry. You may see multiple hardware ID values, separated by commas, listed for the device.


This behavior is by design.


See the Windows 95 DDK for more information on hardware IDs and inf files.
