What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/operation_mode
Date: March 2010
Contact: Bruno Prémont <bonbons@linux-vserver.org>
Description: Make it possible to switch the PicoLCD device between LCD
(firmware) and bootloader (flasher) operation modes.
Reading: returns list of available modes, the active mode being
enclosed in brackets ('[' and ']')
Writing: causes operation mode switch. Permitted values are
the non-active mode names listed when read.
Note: when switching mode the current PicoLCD HID device gets
disconnected and reconnects after above delay (see attribute
operation_mode_delay for its value).
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/operation_mode_delay
Date: April 2010
Contact: Bruno Prémont <bonbons@linux-vserver.org>
Description: Delay PicoLCD waits before restarting in new mode when
operation_mode has changed.
Reading/Writing: It is expressed in ms and permitted range is
0..30000ms.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/fb_update_rate
Date: March 2010
Contact: Bruno Prémont <bonbons@linux-vserver.org>
Description: Make it possible to adjust defio refresh rate.
Reading: returns list of available refresh rates (expressed in Hz),
the active refresh rate being enclosed in brackets ('[' and ']')
Writing: accepts new refresh rate expressed in integer Hz
within permitted rates.
Note: As device can barely do 2 complete refreshes a second
it only makes sense to adjust this value if only one or two
tiles get changed and it's not appropriate to expect the application
to flush it's tiny changes explicitely at higher than default rate.

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.

What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/firmware_version
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
This file is readonly.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/kone_driver_version
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.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/profile[1-5]
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.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/settings
Date: March 2010
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
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
data.
What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/startup_profile
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
4 20g
