Abstract: Some techniques are described herein for a setup component of a controller to add accessories to a new ecosystem (e.g., a grouping of one or more accessories and one or more controllers and/or a grouping of one or more accessories to an application) that are already added to another ecosystem. Such techniques can include the setup component maintaining a list of accessories for which the setup component has added to the other ecosystem. Using the list, the setup component adds the accessories in the list to the new ecosystem through communications with the accessories and an application corresponding to the new ecosystem.

Abstract: Some techniques are described herein for initially setting up an accessory with a controller. Such techniques have a setup component of a controller establish a relationship with the accessory and facilitate establishment of relationships between applications of the controller and the accessory. In some examples, the setup component causes an accessory management credential to be installed on the accessory so that the accessory can be configured by the setup component to establish a relationship with an application in communication with the setup component. In some examples, such communication between the application and the accessory occurs without further interactions with the setup component.

Abstract: Improved approaches for users of computing devices to interact with graphical user interfaces are described. According to one aspect, a rotational user action supplied by a user at a user input device is transformed into linear action with respect to a graphical user interface. According to another aspect, a portion of an extended list of items is displayed by a graphical user interface and, through rotational user actions at a user input device, the portion of the list being displayed can be varied with welcomed ease of use. Although the type of computing device can vary, the improved approaches are particularly well-suited for use with a portable media player.
