Patent ID: 8578378

Claim:
An apparatus comprising: circuitry to determine compatibility, at least in part, of a device with at least one process intended to interact with, at least in part, the device, the compatibility being determined by the circuitry based at least in part upon at least one device feature set of the device, the at least one device feature set comprising at least one certain feature set and at least one additional feature set; if the device is incompatible, at least in part, with the at least one process, the circuitry is to identify, at least in part, the device to the at least one process by providing to the at least one process at least one identifier that identifies the at least one device feature set as comprising solely the at least one certain feature set, the at least one certain feature set being of a relatively earlier produced device version, the at least one relatively earlier produced device version being relative to at least one relatively later produced device version that comprises the at least one additional feature set and the at least one certain feature set; and if the device is compatible with the at least one process, the circuitry is to identify, at least in part, the device to the at least one process by providing to the at least one process at least one different identifier that identifies the at least one device feature set as comprising the at least one additional feature set and the at least one certain feature set that are comprised in the at least one relatively later produced device version, wherein: the at least one device feature set comprises a first register set and a first configuration space; the at least one process is capable of interacting with, at least in part, a second register set and a second configuration space; and if the device is incompatible, at least in part, with the at least one process, the circuitry is to identify, at least in part, the device in a manner that indicates that the compatible interaction is possible via the second register set and the second configuration space.
