The code was checking for a value of exactly 1, while the Synaptics
docs at http://www.synaptics.com/sites/default/files/511-000275-01rA.pdf
say:
Extended Model ID. This query returns the product ID, additional
capability bits, and additional bits to widen the infoSensor
field. infoSensor is a part of the Model ID query (query $03).
The Extended Model ID query is only present if nExtendedQueries
is *greater than* or equal to 1.
