Vendor-specific peripheral device class identifiers

A peripheral device class identifier is generated for a class of peripheral devices, and is used to identify a setup record that indicates how to install or otherwise set up the class of peripheral devices on a computing device. The peripheral device class identifier is a combination of three components: a vendor identifier, a namespace identifier, and a namespace entry identifier. The vendor identifier is an identifier of the vendor of the class of peripheral devices. The namespace identifier is an identifier of different collections or groups of types of peripheral devices or types of functionality of peripheral devices. The namespace entry identifier is an identifier of a particular type of peripheral device (or particular functionality) of the different collections or groups of types of peripheral devices (or types of functionality of peripheral devices).
