No, the SDK does not work with the so-
called CM11 USB (it isn�t an X10 product).
The CM11 USB is standard CM11 that is
bundled with a 3rd party USB to serial
cable.
As far ask I know, the SDK will only work
with true X10 brand USB controllers (such
as the CM15A and CM19A). It will not work
with the CM11 or CM17 (even though the CM17
is controlled by X10nets.exe). It also
will not work with third party controllers.
