That specific warning is caused by the INF not having and matching hardware
or compatible IDs with what the devnode reports. As far as PnP is concerned
the INF is not compatible because no IDs match. That particular warning
isn't related to signing. If you know the INF is compatible with the device
(it sounds like you do know because you own the INF) then you should add at
least one of the device's hardware or compatible IDs to the INF.

Thanks for the reply.

I had changed the hardware/compatible ID in INF file and now able to
install the without the warning message.
