The easiest way would be to use the .INF file of a driver that supports the hardware you're using. So, if FW177.30 is the driver you want to use, but FW177.31 is the one that supports your hardware, you pick copy the .INF file of the FW177.31 driver and place it in the extracted FW177.30 folder.
Use a driver version as close to the one you want to use, though.
