I was able to build this and test on the controllers I have. After
modprobing 'ledtrig-timer', I was able to 'echo timer > trigger' in the
appropriate led directory and confirm that leds blinked without additional
USB traffic seen by USBMON.

DS3 SixAxis - mostly worked, although I hade to set a led to 0, before I
could set to 1 (otherwise all leds just did automatic blinking). I was
able to:
blink single led
blink led while other was statically on
blink multiple leds with different timing
blinking sometimes got confused, setting trigger to none and back to timer
resolved.

DS4 - Worked as descibed in patch, but I feel behaviour is confusing. I
was able to:
blink single led
unable adjust other led whilst blinking (blinking stopped, or wrong colour
started blinking)

3rd Party Intec - Was unable to get any controlled blinking. As previously
mentioned all leds flash (automatic, as if first plugged in) whenever all
leds are turned off.
I can control all leds in a static on/off mode, but can't set any
blinking/timer behaviour

Let me know if there's any other testing I can do,
Simon.
