So don't use /dev/input/mice for "all" mice, just for the USB mouse
that you plug in. Use /dev/input/eventX for the synaptics trackpad.
Here is what I have for my two mouse entries in xorg.conf, and it
hotplugs USB mice perfectly:
Section "ServerLayout"
Identifier "Default"
Screen 0 "LCD"
InputDevice "touchpad" "CorePointer"
InputDevice "usbmouse"
InputDevice "keyboard" "CoreKeyboard"
EndSection
Section "InputDevice"
Identifier "touchpad"
Driver "synaptics"
Option "Device" "/dev/input/trackpad_evt"
Option "Protocol" "event"
Option "SHMConfig" "On"
Option "LeftEdge" "1500"
Option "TopEdge" "1300"
Option "RightEdge" "5400"
Option "BottomEdge" "4400"
Option "EdgeMotionUseAlways" "On"
Option "EdgeMotionMinZ" "70"
Option "EdgeMotionMaxZ" "85"
Option "EdgeMotionMinSpeed" "25"
Option "EdgeMotionMaxSpeed" "700"
Option "MinSpeed" "0.0"
Option "MaxSpeed" "0.3"
Option "AccelFactor" "0.3"
Option "UpDownScrolling" "On"
Option "LeftRightScrolling" "On"
Option "Buttons" "8"
Option "ZAxisMapping" "4 5"
EndSection
Section "InputDevice"
Identifier "usbmouse"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mice"
Option "Buttons" "8"
Option "ZAxisMapping" "4 5"
Option "SendCoreEvents" "On"
EndSection
I use a custom udev rule to make the "trackpad_evt" device, otherwise
my keyboard and trackpad event nodes get mixed up between event0 and
event1:
BUS=="input", KERNEL=="event*", SYSFS{phys}=="isa0060/serio1/input0",
NAME:="input/trackpad_evt", SYMLINK="input/%k"
Either this, or you have to wait for a version of X.org that truly
supports mouse hot plugging.
