is accessed by reading any of the numerous

cFM2Devices class—An object class that manages a
collection of cFM2Device objects for application code
indexing. The collection is managed internally within the
cFM2Listener object. cFM2Device objects are added to
the collection with every meter USB connect event.

index key. cFM2Device objects are removed from the
collection with every meter USB disconnect event. The
collection is passed to the cFM2Notify object with every
meter USB connect or disconnect event.
