+Description: The integer value of this attribute ranges from 1-5.
+ When read, this attribute returns the number of the actual
+ profile which is also the profile that's active on device startup.
+ When written this attribute activates the selected profile
+ immediately.

+Description: The keyboard can store short macros with consist of 1 button with
+ several modifier keys internally.
+ When written, this file lets one set the sequence for a specific
+ button for a specific profile. Button and profile numbers are
+ included in written data. The data has to be 24 bytes long.

+Description: The keyboard lets the user deactivate 5 certain keys like the
+ windows and application keys, to protect the user from the outcome
+ of accidentally pressing them.
+ The integer value of this attribute has bits 0-4 set depending
+ on the state of the corresponding key.
+ When read, this file returns the current state of the buttons.
+ When written, the given buttons are activated/deactivated
+ immediately.

+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: The keyboard has a condensed layout without num-lock key.
+ Instead it uses a mode-key which activates a gaming mode where
+ the assignment of the number block changes.
+ The integer value of this attribute ranges from 0 (OFF) to 1 (ON).
+ When read, this file returns the actual state of the key.
+ When written, the key is activated/deactivated immediately.
