docs: This function code allows reading the identification and additional information relative to the
  physical and functional description of a remote device, only.
  The Read Device Identification interface is modeled as an address space composed of a set
  of addressable data elements. The data elements are called objects and an object Id
  identifies them.
  The interface consists of 3 categories of objects :
   Basic Device Identification. All objects of this category are mandatory : VendorName,
  Product code, and revision number.
   Regular Device Identification. In addition to Basic data objects, the device provides
  additional and optional identification and description data objects. All of the objects of
  this category are defined in the standard but their implementation is optional .
   Extended Device Identification. In addition to regular data objects, the device provides
  additional and optional identification and description private data about the physical
  device itself. All of these data are device dependent.
