ASSOCIATION OF AN INPUT AND OUTPUT OF A PERIPHERAL DEVICE IN A COMPUTING SYSTEM
A method on a computing system for associating an output of a coupled peripheral device to an input of the peripheral device is provided. The method comprises receiving a descriptor configuration input from the coupled peripheral device describing attributes of the peripheral device and an association between the input of the peripheral device and the output of the peripheral device; providing peripheral device classes of associated input attributes including associated output attributes of the peripheral device; and informing an instantiated application of attributes of the peripheral device through classes. In another implementation, the method comprises providing an interface set comprising associated input attributes and output attributes of a peripheral device; using an input logical layer to access attributes of an interface set for an input of the peripheral device including associated output attributes of the peripheral device; selecting an attribute associated with the input; and setting the selected attribute of the peripheral device. In yet another implementation, a computing system configured to be coupled to a peripheral device comprising an input and an associated output is provided. The computing system comprises an input logical layer configured to receive descriptor configuration information from the peripheral device and build interface sets including attributes of the input of the peripheral device and the associated output. The input logical layer uses the interface sets to select and set attributes of the output of the peripheral device.
