The ThingM blink(1) is an open source hardware USB RGB LED. It contains an internal EEPROM, allowing to configure up to 12 light patterns. A light pattern is a RGB color plus a fade time. This driver registers a LED class instance with additional sysfs attributes to support basic functions such as setting RGB colors, fade and playing. Other functions are still accessible through the hidraw interface. At this time, the only documentation for the device is the firmware source code from ThingM, plus a few schematics. They are available at: https://github.com/todbot/blink1 This patch is version 3. It updates the name of the source file, the driver and the led sysfs entry, according to comments from Jiri Kosina and Simon Wood.
