Hi,
I have 11.1 installed on Asus Z96S laptop. Kernel boots with these options: nolapic and pci=nomsi (without them system freezes).
Logitech MX400 mouse not working at all while USB ports works well with other hardware. Ubuntu with same boot options worked with mouse normally.
I’d compare Ubuntu’s and Opensuse’s mouse section in /etc/X11/xorg.conf to see what’s different, probably the driver used, possibly a wrong identifier. In opensuse 11.0 a logitech USB optical mouse recognized as “logitech USB-PS/2 Optical Mouse” xorg.conf has:
Section "InputDevice"
Driver "mouse"
Identifier "Mouse[1]"
Option "Buttons" "5"
Option "Device" "/dev/input/mice"
Option "Name" "Logitech USB-PS/2 Optical Mouse"
Option "Protocol" "explorerps/2"
Option "Vendor" "Sysp"
Option "ZAxisMapping" "4 5"
EndSection
Here it uses the standard mouse driver, nothing special.
And try running dmesg in a terminal right after plugging the mouse, see what messages you get.
Thanks for reply, dmesg output was quite big, so I am copying the part related to mouse (I think that is related 
):

@brunomci -
We are both working the same problem in two different threads on this problem. Check my post at 11.1 freezes - Page 3 - openSUSE Forums.
@ Mingus: OK, will do.
@OP: Found this howto: Logitech-MX400 - openSUSE
It’s for 10.3, but may be of some help.
Thx for the helpful link. Check the last posts at the other thread. Actually, sax2 did correctly configure the mouse. Apparently the xorg.conf was over-written and the necessary InputDevice sections were missing.
