+What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/actual_dpi
+Date: March 2010
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: It is possible to switch the dpi setting of the mouse with the
+ press of a button.
+ When read, this file returns the raw number of the actual dpi
+ setting reported by the mouse. This number has to be further
+ processed to receive the real dpi value.

+Date: March 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 138 means 1.38

+Date: March 2010
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: When read, this file returns the driver version.
+ The format of the string is "v<major>.<minor>.<patchlevel>".
+ This attribute is used by the userland tools to find the sysfs-
+ paths of installed kone-mice and determine the capabilites of
+ the driver. Versions of this driver for old kernels replace
+ usbhid instead of generic-usb. The way to scan for this file
+ has been chosen to provide a consistent way for all supported
+ kernel versions.
+ This file is readonly.

+Date: March 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 holds informations like button
+ mappings, sensitivity, the colors of the 5 leds and light
+ effects.
+ When read, these files return the respective profile. The
+ returned data is 975 bytes in size.
+ When written, this file lets one write the respective profile
+ data back to the mouse. The data has to be 975 bytes long.
+ The mouse will reject invalid data, whereas the profile number
+ stored in the profile doesn't need to fit the number of the
+ store.
+

+Date: March 2010

+Description: When read, this file returns the settings stored in the mouse.
+ The size of the data is 36 bytes and holds information like the
+ startup_profile, tcu state and calibration_data.
+ When written, this file lets write settings back to the mouse.
+ The data has to be 36 bytes long. The mouse will reject invalid

+Date: March 2010
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: The integer value of this attribute ranges from 1 to 5.
+ 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: March 2010
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: The mouse has a "Tracking Control Unit" which lets the user
+ calibrate the laser power to fit the mousepad surface.
+ When read, this file returns the current state of the TCU,
+ where 0 means off and 1 means on.
+ Writing 0 in this file will switch the TCU off.
+ Writing 1 in this file will start the calibration which takes
+ around 6 seconds to complete and activates the TCU.
+
+What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/weight
+Date: March 2010
+Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
+Description: The mouse can be equipped with one of four supplied weights
+ ranging from 5 to 20 grams which are recognized by the mouse
+ and its value can be read out. When read, this file returns the
+ raw value returned by the mouse which eases further processing
+ in other software.
+ The values map to the weights as follows:
+
+ VALUE WEIGHT
+ 0 none
+ 1 5g
+ 2 10g
+ 3 15g
