The only difference I see is that you got a different acceleration profile
with a negative -0.4, while mine is +0.4.
What do you get for feedback parameters? Mine are:
volodya@iridium:~$ xinput --get-feedbacks 11
1 feedback class
PtrFeedbackClass id=0
accelNum is 2
accelDenom is 1
threshold is 4
(11 is the id of my trackball).

The man page is pretty opaque to someone who has not seen this b4 so I have
no idea how to modify anything above. Is something totally fubar?
Thank you Vladimir Dergachev.
Cheers, Gene Heskett, CET.
