psmouse.c in Kernel fails but succeeds as Module

psmouse.c in Kernel fails but succeeds as Module

[jt]

Was using 2.6.11.4 and the GlidePoint worked there just fine

In 2.6.14.2 the Alps GlidePoint Mouse stopped being detected when
I compile Kernel with

CONFIG_MOUSE_PS2=y

After boot up

cat of /proc/bus/input/devices  displays:

I: Bus=0010 Vendor=001f Product=0001 Version=0100

H: Handlers=mouse0 event2
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103



However, when  I compile Kernel with

CONFIG_MOUSE_PS2=m

and after boot up execute
modprobe psmouse
manually

the Alps GlidePoint is detected thus

I: Bus=0010 Vendor=001f Product=0001 Version=0100
N: Name="PC Speaker"
P: Phys=isa0061/input0
H: Handlers=kbd event0

I: Bus=0011 Vendor=0002 Product=0008 Version=0000
N: Name="PS/2 Mouse"
P: Phys=isa0060/serio1/input1
H: Handlers=mouse1 event3
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=3

B: EV=f
B: KEY=420 0 70000 0 0 0 0 0 0 0 0
B: REL=3
B: ABS=1000003

and GlidePoint Works fine in Console Mode and X etc.

I have my work around for the problem, but wondered if
someone like Dimitry T. would like me to perform a little
debugging and send them the output so others wont have
to face this problem.

Yes, the 2.6.11.4 had
CONFIG_MOUSE_PS2=y

I dont take the kernel message feed so please reply to me
and I will keep a lookout in  LMKL

thanks
jt

This is most likely USB legacy emulation screws up touchpad detection.
If you boot with "usb-handoff" on the kernel command line it shoudl
detect ALPS even if psmouse is built-in and not a module.

One of these days we will turn it on by default...

Would be easier if you CC me if you want me to see your message faster ;)
