+ * There are two hidpp protocols in use, the first version hidpp10 is known
+ * as register access protocol or RAP, the second version hidpp20 is known as
+ * feature access protocol or FAP
+ *
+ * Most older devices (including the Unifying usb receiver) use the RAP protocol
+ * where as most newer devices use the FAP protocol. Both protocols are
+ * compatible with the underlying transport, which could be usb, Unifiying, or
+ * bluetooth. The message lengths are defined by the hid vendor specific report
+ * descriptor for the HIDPP_SHORT report type (total message lenth 7 bytes) and
+ * the HIDPP_LONG report type (total message length 20 bytes)
+ *
+ * The RAP protocol uses both report types, whereas the FAP only uses HIDPP_LONG
