  It sounds like you are getting data from the USB mouse. I take it that
  if you start X, and you don't move the mouse, the pointer sits still
  in the middle of the screen? It is only when you move the mouse that
  it leaps up to the top left corner and bounces around?

  This sounds like it is the wrong protocol. You probably want to read
  /usr/share/doc/xserver-xfree86/README.mouse.gz.

  In your XF86Config-4 file, in the InputDevice corresponding to the
  mouse I would try the following lines (not all at the same time
  though):
  Option "Protocol" "Auto"
  Option "Protocol" "usb"
  Option "Protocol" "PS/2"

  It sounds like the Option "Device" is set ok, as you are getting data
  from the mouse (an making the pointer jump to the top left of the
  screen).

  Also, does the log from X starting up show anything mentioning the
  mouse?
