+Description:    The integer value of this attribute ranges from 0-4.
+                When read, this attribute returns the number of the active
+                profile.
+                When written, the mouse activates this profile immediately.
+                The profile that's active when powered down is the same that's
+                active when the mouse is powered on.

+Description:    When read, this file returns the raw integer version number of the
+                firmware reported by the mouse. Using the integer value eases
+                further usage in other programs. To receive the real version
+                number the decimal point has to be shifted 2 positions to the
+                left. E.g. a returned value of 121 means 1.21

+Description:    The mouse can store 5 profiles which can be switched by the
+                press of a button. A profile is split in settings and buttons.
+                profile_buttons holds informations about button layout.
+                When written, this file lets one write the respective profile
+                buttons back to the mouse. The data has to be 23 bytes long.
+                The mouse will reject invalid data.
+                Which profile to write is determined by the profile number
+                contained in the data.
+                This file is writeonly.
