Yes, that is correct. Basically, the trackpad is to regular USB mice as 
a winmodem is to a regular modem: you just get a grid of pad pressures, 
and have to go around taking weighted averages to get the mouse 
position, figure out the position delta from last time, detect if there 
are two fingers on the pad to implement scrolling, etc. This same device 
also has an ADB attachment; the later model ADB trackpads can be put 
into a mode where they do the same thing by setting their handler code 
appropriately.
