"auto" instructs the mouse daemon that when it sees a ps/2 port to use
the ps/2 protocol, when it sees a serial port to probe for that, when
it sees a usb port to setup for usb protocol.
It is preferable particularly in a doc like this because it applies

You don't need to worry about it. Any problems between moused and
X's support for the sysmouse protocol are something an ordinary user
probably will never see. This can be ignored as the problem of the
moused authors and X authors.
What an ordinary user needs to be concerned with is if moused is
correctly talking to their rodent.

It's off whenever more than 2 buttons are detected - a wheel mouse always
has more than 2 - but this might prevent a useless error message in the
