Can I speculate? Perhaps the 32 foot cord is doubling the spec with the repeater end. That end is special and lights up. I think it uses power from the nearest USB device to strengthen the signal. It is interesting that it is almost precisely double spec, isn't it? Everyone says 15-16 feet is the limit, but this cord is exactly twice. And you get more than the 32 feet b/c you plug yet another USB cord into the end of the first.
