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.
|
||||
This file is writeonly.

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.
