+Description:
+                The /sys/devices/.../firmware/description attribute contains a string
+                that describes the device as provided by the _STR method in the ACPI
+                namespace.  This attribute is read-only.  If the device does not have
+                an _STR method associated with it in the ACPI namespace, this
+                attribute is not present.
