What: /sys/class/leds/blink1::<serial>/rgb
Date: January 2013
Contact: Vivien Didelot <vivien.didelot@savoirfairelinux.com>
Description: The ThingM blink1 is an USB RGB LED. The color notation is
3-byte hexadecimal. Read this attribute to get the last set
color. Write the 24-bit hexadecimal color to change the current
LED color. The default color is full white (0xFFFFFF).
For instance, set the color to green with: echo 00FF00 > rgb
What: /sys/class/leds/blink1::<serial>/fade
Date: January 2013
Contact: Vivien Didelot <vivien.didelot@savoirfairelinux.com>
Description: This attribute allows to set a fade time in milliseconds for
the next color change. Read the attribute to know the current
fade time. The default value is set to 0 (no fade time). For
instance, set a fade time of 2 seconds with: echo 2000 > fade
What: /sys/class/leds/blink1::<serial>/play
Date: January 2013
Contact: Vivien Didelot <vivien.didelot@savoirfairelinux.com>
Description: This attribute is used to play/pause the light patterns. Write 1
to start playing, 0 to stop. Reading this attribute returns the
current playing status.

* PS1000 (USB gamepad):
* Fixes the HID report descriptor by removing a non-existent axis and
* clearing the constant bit on the input reports for buttons and d-pad.
* (This module is based on "hid-ortek".)
*
* Copyright (c) 2012 Andreas Hübner
*
* R.A.T.7, M.M.O.7 (USB gaming mice):
* Fixes the mode button which cycles through three constantly pressed
* buttons. All three press events are mapped to one button and the
* missing release event is generated immediately.
*
