+Date:		December 2012
+Contact:	Stefan Achatz <erazor_de@xxxxxxxxxxxxxxxxxxxxx>
+Description:	The mouse can store 5 profiles which can be switched by the
+		press of a button. actual_profile holds number of actual profile.
+		This value is persistent, so its value determines the profile
+		that's active when the mouse is powered on next time.
+		When written, the mouse activates the set profile immediately.
+		The data has to be 3 bytes long.
+		The mouse will reject invalid data.
