Asked By mariacblanche 20 points N/A Posted on - 06/09/2012

USB 3.0 is the new technology for USB controllers. Recently manufactured computers are now coming out with USB 3.0.

What's the power requirement for this device? It is supposed to have a better transfer speed thus would require another device or 2 that will work well along with it.

USB 3.0 power requirements needed

The Power efficiency of the USB 3.0 is that the host computer or the device can initiate a power savings state when idle this progressively lower power management states when the link partners are idle. The Streaming for bulk transfers is supported for faster performance. This transfers allows devices to enter low power link states between service intervals and this communicates their latency tolerance which provides better power performance.

This doesn't need another device that can work alone, any high-bandwidth device that works with your USB 2.0 works better if you update with USB 3.0 support. USB 3.0 contains 2 hub, one that enumerates as a Super Speed hub, and second, that enumerates as a regular high-speed hub. Remember that USB 3.0 is still compatible with the USB 2.0.
