What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/konepure/roccatkonepure<minor>/actual_profile
Date: December 2012
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The mouse can store 5 profiles which can be switched by the
press of a button. actual_profile holds number of actual profile.
This value is persistent, so its value determines the profile
that's active when the mouse is powered on next time.
When written, the mouse activates the set profile immediately.
The data has to be 3 bytes long.
The mouse will reject invalid data.

Date: December 2012
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When written, this file lets one select which data from which
profile will be read next. The data has to be 3 bytes long.
This file is writeonly.

Date: December 2012
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When read, this file returns general data like firmware version.
When written, the device can be reset.
The data is 6 bytes long.

Date: December 2012
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The mouse can store a macro with max 500 key/button strokes
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 2082 bytes long.
This file is writeonly.

Date: December 2012
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
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 information about button layout.
When written, this file lets one write the respective profile
buttons back to the mouse. The data has to be 59 bytes long.
The mouse will reject invalid data.
Which profile to write is determined by the profile number
contained in the data.
Before reading this file, control has to be written to select
which profile to read.

Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
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_settings holds information like resolution, sensitivity
and light effects.
When written, this file lets one write the respective profile
settings back to the mouse. The data has to be 31 bytes long.
The mouse will reject invalid data.
Which profile to write is determined by the profile number
contained in the data.
Before reading this file, control has to be written to select

Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The mouse has a tracking- and a distance-control-unit. These
can be activated/deactivated and the lift-off distance can be
set. The data has to be 6 bytes long.
