I am trying to reassign the functions on the buttons of my Logitech G700 mouse. Using xinput --list, I see that this counts as two devices (four if you include the wired/wireless differences).

48 will@will-laptop ~]$xinput --list

⎡ Virtual core pointer                          id=2    [master pointer  (3)]

⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

⎜   ↳ Microsoft Natural® Ergonomic Keyboard 4000        id=10   [slave  pointer  (2)]

⎜   ↳ SynPS/2 Synaptics TouchPad                id=15   [slave  pointer  (2)]

⎜   ↳ Logitech USB Receiver                     id=17   [slave  pointer  (2)]

⎜   ↳ Logitech USB Receiver                     id=18   [slave  pointer  (2)]

The problem is that there are non-default assignments to the buttons, so xev doesn't show things like "button 12" or whatever, it just shows the keystrokes assigned to the button (i.e. KeyPress Ctrl_L, KeyPress "w", KeyRelease Ctrl_L, KeyRelease "w"). It doesn't show the device and so I'm not sure how to reassign what the key should do. Also, as near as I can tell, there is no way to do a hardware reset of the on-board memory profiles, so I can't reset the mouse to actually give me a "button 7" or whatever.

I am using Ubuntu 13.10.

Here is what I get from xev when I try the "tilt wheel to left" button.
