In this review now(that quickly received famoussignificant public attention review), a Google engineer pointed out a flaw in the cable, that, according to him can be "potentially damaging the USB hub or charger".

From the same review, "a value of 56 kΩ ± 5% shall be used, in order to provide tolerance to IR drop on V BUS and GND in the cable assembly". Could someone shed some light on this and explain how a bad cable could actually damage a hub or charger and why the 10 kΩ resistor used in this particular cable does not suffice to prevent this?

How a bad USB cable that doesn't follow the spec can damage the charger/hub?
