attribute.

@ -8,3 +8,14 @@ Description: The integer value of this attribute ranges from 0-4.
When written, this file sets the number of the startup profile
and the mouse activates this profile immediately.
Please use actual_profile, it does the same thing.

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.
