I read some articles regarding added power, and I also equipped myself with a Y cable to power a USB device.
But I left it alone: basically I believe that nowadays a manufacturer who sells a USB device like this, which has more than excellent performance, has this situation well in mind, has already done the tests and certainly if he hasn't considered necessary to proceed differently is because he probably didn't consider it a problem, or better yet he didn't consider it necessary to equip the devices with additional solutions.
