Is the same model that has a known problem of keycodes interpretation. I found a solution thanks to a guy called Colin Svinger that made a very complete post speaking deeply about this problem, you can find it on his blog: http://goo.gl/JcdvxG
That solution works great if you have an 101-key standard layout but mine has an 102-key layout, so many keys differs from his driver and I had to rebuild my own based on it but I haven't made it public by now. Tell me if you need my version, regards.
