                 When written, this file sets the number of the startup profile
                 and the mouse activates this profile immediately.

+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
+                This file is readonly.
+                Please read binary attribute info which contains firmware version.
