SYMPTOMS
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.
CAUSE
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.
RESOLUTION
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.
STATUS
This behavior is by design.
