no response from the most generic 3-button mouses

[Dan Jacobson <jidanni@jidanni.org>]

In XF86Config-4, these work fine for my Trackman Marble+:
Option "Device" "/dev/ttyS1"
Option "Protocol" "IntelliMouse"
But when I instead attach the most common simplest 3 button mouses,
I get no response from the mouses at all. mdetect doesn't detect them,
moving around the mouse or not, yes with xdm stopped, using just the
console. mdetect detects the Trackman Marble+ fine.  No, I don't have
gpm or imwheel installed.  Saying
# Option "Protocol" "MouseSystems"
# Option "Protocol" "Microsoft
doesn't help.  I don't think these matter
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
when trying to get the least response from the mouse, so I didn't
remove them.

For instance, I'm talking about mouses like this:
