Anecdotally, I have a laptop IDE drive enclosure with a USB interface, & the supplied cable has *two* Series A USB connectors in order to provide sufficient power to the drive. On occasion, I have forgotten to plug one connector in, & sometimes it works, but other times it is apparent by the sound that the drive is having problems spinning at a constant rate. Having two connections simply ensures sufficient power is available for more (common) situations. Jim
