| May 6, 2011 at 7:29 | comment | added | AndrejaKo | 1. The power isn't mentioned anywhere in the question. 2. Same thing could happen to USB 2.0 devices, because one port can't power whole hub. 3. You can't assume that a device will decrease it's transfer speed because of low power condition. It may refuse to work at all or it may attempt to save power in some other way. | |
