What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/kovaplus/roccatkovaplus<minor>/actual_cpi
Date: January 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The integer value of this attribute ranges from 1-4.
When read, this attribute returns the number of the active
cpi level.
This file is readonly.

Date: January 2011
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 active
profile.
When written, the mouse activates this profile immediately.
The profile that's active when powered down is the same that's
active when the mouse is powered on.

Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The integer value of this attribute ranges from 1-10.
When read, this attribute returns the number of the actual
sensitivity in x direction.

Date: January 2011
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

Date: January 2011
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 23 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.
