Thank you for your patch. There is something to discuss/improve.

Your description mentions 8 buttons, so maybe it should be 8 here? Or
description needs a fix?
Driver just handle maxima 4 buttons for general application, but the the
above description is truly hardware capability with 8 buttons support.
Then it should be 8.
Best regards,
Krzysztof
Thanks. I will revise it in v2 patch.
