Configuration Missing

Hi,

I install mime detect module in my server and also add necessary conf to the settings.php file and also enable that module.But when i try to configure in "Mime Detection" i get the following message
"The MimeDetect module is using PHP's fileinfo extension to detect MIME types. There are no settings for the extension."

Is there any thing i missed out or needs to be configure.any one guide me do this.

Thanks
