Thanks Windoze. I found it before I read your post.
I made the following change
# Option "Device" "/dev/mouse"
Option "Device" "/dev/input/mice"
#For scrolling you will also need to add:
#Option ZAxisMapping "4 5"
Logging out made no difference. Restarting, x refused to start until I commented out the ZAxisMapping option. The error pointed to "4 5" saying something about 1 or 2 quotes were need and it was an invalid keyword. Wished I could have copy/paste in tui!
I still don't have wheel.
I did verify that I had "/dev/input/mice" before I made the change.
