[Techtalk] Logitech PS/2 mouse under 2.6

[Mary]

Hey everyone,

I'm struggling a bit to get my optical Logitech wheel mouse working
under Linux 2.6. It simply doesn't work -- X shows a mouse pointer but I
can't move the mouse. The mouse works fine under a 2.4 kernel and under
Windows 2000.

Details:

 Distro: Debian unstable, all up to date (unless the Australian mirrors
 are behind)

 Kernel: 2.6.2 (Debian build 2.6.2-1-686)

 /proc/bus/input/devices shows:
    I: Bus=0011 Vendor=0002 Product=0005 Version=0055
    N: Name="ImPS/2 Logitech Wheel Mouse"
    P: Phys=isa0060/serio1/input0
    H: Handlers=
    B: EV=7 
    B: KEY=70000 0 0 0 0 0 0 0 0 
    B: REL=103 

I've successfully modprobed the psmouse module, the dmesg output was:

input: ImPS/2 Logitech Wheel Mouse on isa0060/serio1

However, neither /dev/psaux or /dev/input/mice exist (XFree gives a "no
such device" error message).

Here's the relevant section of my XF86Config-4 (I'm not using debconf to
manage it because I'm using Xinerama):

Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ImPS/2"
	Option		"Emulate3Buttons"	"true"
	Option		"ZAxisMapping"		"4 5"
EndSection

I've also tried setting the Device to be "/dev/psaux" and the Protocol
to be "ExplorerPS/2".
