The pvrusb2 driver currently supports two variants of the Hauppauge PVR USB2. However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.
