Because when I did try my application on Windows it working correctly.

Can you give do some debugging and try to tell exactly what is failing?[/quote]
Simple try uploading a csv file,
mimes.php has the exact type but it just does not upload,
with valums server-side validation works too[/quote]
This doesn't tell anything other than "it doesn't work for me".
Try dumping $this->upload->file_type after it fails and tell it's value. Also try editing the library and put some echo/var_dump/whatever somewhere in _file_mime_type() to see which detection method is used.
