epIn->DIEPCTL |= USB_OTG_DIEPCTL_EPDIS;
while (epIn->DIEP...
Of course just as i wrote the angry poist, i figured it out(turns out that the synopsys controller is utter crap and it is VERY VERY EASY to wedge it into a weird state)for example, try to set EPDIS twice in a row. until you power cycle the controlle...
