+physical device. Typically, this interface is different for each device family
+and, therefore, the device driver framework does not require a particular
+type of interface. The only requirement is that the physical channel class
+is derived from <xref href="GUID-4FCB6127-84F3-38F6-8AD2-FC3B94D67DA3.dita"><apiname>DBase</apiname></xref>. It is up to the driver writer to
