Razer black widow in ubuntu?

Question

ubuntu

Hi all! I own a Razer Black Widow
keyboard and I'm also a ubuntu user. And yes! I have a question. If you notice, then the keyboard has a number of additional keys m1-m5. How to make them work? I followed this manual. I did everything as described in the console gives:

WRITING SET_REPORT
OK

But in the end nothing works.
Those who faced a similar problem or maybe you just know how to solve it, please tell me.
