Well, trouble is that you can look (with your eyes) at your device and see the
number of LEDs... This is something we cannot do with the driver. 
(Unless we find a EEPROM field which stores the # of LEDs and 
maybe even what they are used for?)

4 is just a "save" guess which should cover most - if not all - customer devices.
