What about digitizing tablets? They would want to be connected by ADB,
but would want to use absolute positioning, not the relative positioning
of a mouse.

There have also been some controls that hide the mouse cursor while you 
adjust a value using the mouse, then it repositions the mouse cursor
to where you started when you let up on the button. Look at the 
"numerical" in Opcode or Intelligent Music software.
