Two packs of US-05 should be plenty of yeast regardless of shaking the carboy or using an air stone to aerate, and you said you pitched more after you put the beer into secondary? I might not have transferred after day 4 I usually wait 10 days. I am not sure how you raised your temp with the controller but I gradually increase temperature, usually after a few days at the starting temp.
All in all, without knowing your mash schedule and grain build it is hard to say what might be happening. Did you use any ingredients/nonfermentables that typically lead to higher end gravity?
