Here's a link to a guy's site where it appears he gives a full detailed story on how to make that mouse fully functional. Be prepared, the site is horrible on the eyes, so you may need to copy and paste it to read it (though I have my contrast set way down too).
There are also some similar mouse models to yours in the HCL, but not the exact one--when you get yours working, perhaps you could add it to the HCL
