I have a small problem with my ps/2 mouse, it moves too fast, how can i change it's speed to go slower much slower ? (from the setings is at it lowest possible speed)
I have Zephyroth Leopard 10.5.1 AMD the first release. Do i have to modify the ApplePS2Controller.kext ?

I did it but still it moves to fast.
while running kextcache -a i386 -e there was some warning about ACPIPS2Nub.kext about some dependencies.

An optioal A4 Tech WOP-35 made in china
I use an usb mouse but that is wireless, works fine but whenever i realy need it the bateries run out

Author Update #3 @gogo 2008-02-10

Finaly made the mouse move slower

I found the source code for ApplePS2Mouse.kext and changed default _resolution from 150 to 350 dpi now it works fine.

Field Note #1 @Puttabong 2008-01-15

Hmm, that sounds like ps/2 issues, try this kexts:

ACPIPS2Nub.kext
ApplePS2Controller.kext

I attached an archive containing them.

In Terminal, type:

sudo -s
password (your password)

cd /system/library/extensions

chmod -R 755 * && chown -R root:wheel *

cd ..

rm -r Extensions.mkext

kextcache -a i386 -e

reboot

Field Note #2 @naquaada 2008-01-15

what's ACPIPS2Nub.kext ? PS/2 is working fine for me, only the cursor keys weren't working one time.

Field Note #3 @Puttabong 2008-01-15

Hmm, just use an USB Mouse then, make it as much compatible as possible. Mighty Mouse. I love it

Field Note #4 @naquaada 2008-01-15

What mouse type do you have, optical or ball mouse?

Field Note #5 @cheapo 2008-03-11

Hello gogo... I have the same mouse as you and the same problem, my mouse is moving too fast... Problem is I don't have another one, and I'm a total noob at mac programming, so I don't have a clue on how to recompile extensions... Is there any way you could send me the extension you changed so I can use with my mouse?
