 ADUCount
( requires DLL V2.1.0.0 or higher*)
This function counts the number of currently connected ADU
devices.
The function accepts a timeout value (in milliseconds), and
returns the number of currently connected ADUs.
Note that the result does not update as devices are connected
and disconnected.
It is advised that you make a call to ADUCount every time you
need an updated count of connected ADUs.
