Yes, backward/forward button mapping is not 1:1. These buttons works with
Option "ButtonMapping" "1 2 3 6 7" as expected.

But the problem is with 'wheel left/right' buttons. These buttons doesn't 
generate button events, so xev can't see these buttons.
Dec 17 12:46:20 dell kernel: ums_intr_callback:210: sc=0xc61dc800
actlen=8 Dec 17 12:46:20 dell kernel: ums_intr_callback:228: data = 00 00 00 00 00 00 00 ff
Dec 17 12:46:22 dell kernel: ums_intr_callback:210: sc=0xc61dc800
actlen=8 Dec 17 12:46:22 dell kernel: ums_intr_callback:228: data = 00 00 00 00 00 00 00 01

There's no ums_intr_callback:294 events.

What you mean by phrase 'do log2 of the buttons value'? What is the 'log2'?
