Thanks for posting up how to send the scrollup/down - that's great.
You're asking how to send Absolute Position? Much like a tablet/touchscreen?
I think what you need is USBTablet: http://www.espruino.com/USB#tablet
However I don't think that supports a wheel by default! To get that you'll have to make your own HID report descriptor by mashing the wheel's descriptor into the tablet bit...
But at that point my knowledge is at an end - you'll have to consult Google and use some trial and error to figure out what will work.
