In HS2 it was possible to add input options for any device that my plug-in could use to tag information specific to that device using the ConfigDevice function. In HS3, it appears that the ConfigDevice is only used for device's created by that plug-in. For example, in my plug-in (InControl) the user must go into a device select a checkbox they would like presented in the Windows 8/Phone app.

EDIT - never mind I found "SupportsConfigDevicesAll"
