OK, but this means that for some mice the controls in TDE have no effect -
correct?

I use a Benq mouse I bought in 2006 - seems a great hardware - never had
problem with acceleration described - even after latest upgrade to buster.

However I have experienced odd things with cheap mouse and stupid KVM
switch - like sticky keys - mouse not moving - strange messages about USB
in the syslog etc.

Never mind - the thing is - the function in TDE should set the acceleration
the way you do it in .xsetting, but I do not see an option to set for
specific hardware.

I would file a request to update this in future major release.
