+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).

+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.

+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

+Description:	The mouse can store 5 profiles which can be switched by the

+                mappings, sensitivity, the colors of the 5 leds and light

+                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.

+                When read, this attribute returns the number of the profile

+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
