yes, it is documented that scratching off some specific resistor near usb connector helps, it is 5K pull up to vcc by mistake but cpu can drive that pin too after the resistor is removed, have that cheap board too but did not test this yet. and the leak is when driving that pin low which turns off power to external stuff so if not used for anything it may be pulled high to prevent the leak(?)
