HID: roccat: Add support for Roccat Kone[+] v2

Browse Source 
This patch adds support for Roccat Kone[+] gaming mouse. Kone[+] is an enhanced version
of the old Kone with more memory for macros, a better sensor and more functionality.
This driver is conceptual similar to the existing Kone and Pyra drivers.
Userland tools can soon be found at http://sourceforge.net/projects/roccat

What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/actual_profile
Date: October 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When read, this file returns the number of the actual profile in
range 0-4.
This file is readonly.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/firmware_version
Date: October 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
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

What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/macro
Date: October 2010
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.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/profile_buttons
Date: August 2010
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 informations about button layout.
When written, this file lets one write the respective profile
buttons back to the mouse. The data has to be 77 bytes long.
The mouse will reject invalid data.
Which profile to write is determined by the profile number
contained in the data.
This file is writeonly.

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 informations 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 43 bytes long.

Date: October 2010
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.
This file is writeonly.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/startup_profile
Date: October 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The integer value of this attribute ranges from 0-4.
When read, this attribute returns the number of the profile
that's active when the mouse is powered on.
When written, this file sets the number of the startup profile
and the mouse activates this profile immediately.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/tcu
Date: October 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When written a calibration process for the tracking control unit
can be initiated/cancelled.
The data has to be 3 bytes long.

Date: October 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: When read the mouse returns a 30x30 pixel image of the
sampled underground. This works only in the course of a
calibration process initiated with tcu.
The returned data is 1028 bytes in size.
