I don't know if this will help you, but I'll describe how I got my
trackball (a Logitech Marble Mouse USB) to work with FreeBSD
(currently using 5.1). I used xev in X during the process in order to
see what X thought was happening when I pressed various buttons or
moved the trackball on the mouse.
Like you, I use the FreeBSD mouse daemon (moused) in the XF86Config
file (Option "Device" "/dev/sysmouse"). My trackbal has two large
buttons, one on either side, and two smaller buttons located just at
the top side of the larger buttons, one on each side. Those are
normally used for scrolling in Windows or the MacOS.
Although the trackball has only four buttons, I used 'Options
"Buttons" "5"' in XF86Config because I set the mouse daemon to
emulate a third (middle) button with the -3 option.
In addition, I wanted to enable scrolling. So my XF86Config looks like
yours with respect to the following:
Option "ZAxisMapping" "4 5"
Option "Buttons" "5"
So, even though my trackball only has four buttons, I told X that it
has 5 (four physical buttons and an additional virtual middle button
supplied by the mouse daemon, used by pressing both the left and
right buttons at the same time). In addition, because I am asking X
to use the mouse daemon (/dev/sysmouse), I gave the mouse daemon an
extra flag:
-z 4
which tells the mouse daemon to report a z-axis movement (vertical
scrolling) when the fourth button is pressed and held while the
trackball is moved. When X starts and I press the fourth button (the
small button above the large left button) while moving the trackball,
the FreeBSD mouse daemon (moused) reports z-axis movement to X just
as though I were repeatedly pressing a fourth and fifth button for
"up" and "down" scrolling, so the 'Option "ZAxisMapping" "4 5"' in
XF86Config works.
So, to summarize, in my XF86Config file I have:
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "Auto"
Option "Device" "/dev/sysmouse"
Option "Buttons" "5"
Option "ZAxisMapping" "4 5"
EndSection
--notice that there is no 'Option "Emulate3Buttons"' in my XF86Config
file--the FreeBSD mouse daemon does the emulation instead, both on
the command line and for XFree86--
and my /etc/rc.conf file includes:
moused_enable="YES"
moused_type="auto"
moused_port="/dev/ums0"
# the port listed above refers to my USB, not a PS/2, trackball
moused_flags="-3 -z 4"
