The improvement of "SuperSpeed USB" goes far beyond the improvement in transmission speed. In USB 3.0, how to cooperate more harmoniously between devices and computer hosts has also been regarded as a key research direction. On the basis of inheriting the core architecture of USB 2.0, how to utilize the advantages of dual bus mode and enable users to directly experience the advanced performance of USB 3.0 compared to USB 2.0 has become the focus:

USB 3.0 can provide more power when needed, providing 50% -80% more power to support devices that require more power to drive, while devices that charge through USB indicate faster completion of charging.

The new Powered-B interface consists of two additional lines, providing power support of up to 1000 milliamperes. It can completely drive wireless USB adapters, eliminating the need for traditional USB adapters to be connected by cables. Usually, wired USB devices need to be connected to hubs or the computer itself, and with high power support, there is no need for a "cable" to exist.

Automatically reduce power consumption when not needed and switch to USB 3.0. Power consumption is also an important issue to consider, so effective power management is necessary to ensure that the device reduces power consumption when idle.

Large amounts of data stream transmission require faster performance support, and during transmission, devices can transition to a low-power state when idle. You can even spare time to receive other instructions and complete other actions.

In fact, not everything has been updated in the USB 3.0 motherboard, such as the length of cables. When the highest possible throughput is required in certain applications, cables often still become bottlenecks. Although the length of the USB cable is not explicitly specified in the USB 3.0 specification, the cable material and signal quality still affect the transmission effect. Therefore, when transmitting hundreds of megabytes of Big data streams, the cable length should not exceed 3 meters.
