    SysFS interface :

     *  /sys/class/leds/red/device/led_fade (rw)
                        0 : blink
                        1 : fade (default)

     *  /sys/class/leds/red/device/led_intensity (rw)

                                        0 : stock intensity
                        1-100 : 0% to 100% of stock intensity
			Note: Does only work for static led, not fading/blinking !!!

     *  /sys/class/leds/red/device/led_speed (rw)

                                        0 : stock speed
                                        1 : continuous notification light
                         2-12 : 2 = very slow to 20 = very fast
