I got an MS optical mouse, it sucks, dont buy one.
Its unusable as a usb device and barely usable as a ps/2 mouse.

To make the motion of the cursor less jerky i've had to adjust the resolution and sample rates for the mouse in my XF86Config file.
Does anyone know what the optimal settings for this mouse might be?

What are the max resolution and sample rates for most ps/2 / optical mice anyway?

These are the settings im using now:

Driver "mouse"
Option "Protocol" "IMPS/2"
Option "Device" "/dev/psaux"
Option "SampleRate" "100"
Option "BaudRate" "9600"
Option "Buttons" "3"
Option "Resolution" "1000"
Option "ZAxisMapping" "4 5"

Thanks

What distro / version of linux are you using? I have run both Red Hat 7.3, Red Hat 8.0, and Mandrake 9.0 with a MS Optical Mouse (both PS/2 and USB) and it works like a beauty (hot swapping beween my linux boxes and windows boxes too).

Im using mandrake 9.0, its a ms optical mouse blue, this http://www.microsoft.com/hardware/mouse/omb_info.asp
one. Same mouse?

Found the answer while trolling (figuratively of course) through google groups.
The solution is to "rmmod usbmouse" after which the mouse (as a usb mouse) behaves normally.

I take back my previous disrecommendation, seems to work fine
