ButtonMapping for a 5-button mouse

[Phil Endecott]

Dear All,

I've just bought myself an Evoluent Vertical Mouse, and I'm trying to 
get it to work properly with X.  I'm using the Debian package of 6.9.0, 
i.e. xserver-xorg 6.9.0.dfsg.1-4.  I hope this is a good place to ask; 
if not, can you suggest a suitable forum?

This is a USB mouse with three normal buttons, a wheel which is between 
the left and middle buttons, and a fourth button under the thumb.  By 
default, according to xev, the buttons are as follows:

1: left button
2: pressing the wheel
3: middle button
4 & 5: turning the wheel
8: right button
9: thumb button

I'd like to have the following allocation:

1: left button
2: middle button
3: right button
Plus whatever is needed for wheel rotation, presumably 4 and 5.
Pressing the wheel could also act as button 2.
I'm not sure yet about the thumb button, but duplicating the left button 
might be as good a choice as anything.

I think that the key to this must be the ButtonMapping option.  I have 
tried various things and I can reliably change the behaviour of the 
lower-numbered buttons.  But as soon as I have any ButtonMapping option 
present, buttons 8 and 9 are completely disabled (according to xev). 
Even this:

	Option "ButtonMapping" "1 2 3 4 5 6 7 8 9"

Here I'm asking it for a 1-to-1 mapping, but buttons 8 and 9 now report 
nothing in xev.

Here are some clues, in case they help:

- At first I tried 'Protocol USB' (as suggested by man 4x mouse), but 
got an 'unknown protocol' error (sorry, lost the details); I'm now using 
Auto.

- By default, it decided that the mouse had 7 buttons.  This is sort-of 
true, since 6 and 7 are missing.  I have tried with 'Option Buttons 9' 
and it still seems to fail.

Here is an extract from my xorg.conf as it stands at present:

Section "InputDevice"
	Identifier	"Evoluent Vertical Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mouse0"
	Option		"Protocol"		"Auto"
	Option		"Emulate3Buttons"	"false"
	Option		"Buttons"		"9"
	Option		"ZAxisMapping"		"4 5"
	Option		"ButtonMapping"		"1 2 3 4 5 6 7 8 9"
EndSection

and here is what I get in the log:

(**) Evoluent Vertical Mouse: Device: "/dev/input/mouse0"
(**) Evoluent Vertical Mouse: Protocol: "Auto"
(**) Option "CorePointer"
(**) Evoluent Vertical Mouse: Core Pointer
(**) Option "Device" "/dev/input/mouse0"
(**) Option "Buttons" "9"
(**) Option "Emulate3Buttons" "false"
(**) Option "ZAxisMapping" "4 5"
(**) Evoluent Vertical Mouse: ZAxisMapping: buttons 4 and 5
(**) Option "ButtonMapping" "1 2 3 4 5 6 7 8 9"
(**) Evoluent Vertical Mouse: Buttons: 9

Can anyone suggest anything?

Many thanks,
