USB 3.0 also called as SuperSpeed USB will be available soon on ASUS and Gigabyte motherboards. ASUS has also announced an add-in PCIe x4 card with USB 3.0 support, though it is compatible only with its P55 series of motherboards after a BIOS upgrade. Fujitsu is about to release laptops with USB 3.0 support. But Intel has announced that it will not include USB 3.0 in its chipsets until 2011. AMD may not support USB 3.0 until 2011 either. It may be available with Apple products in early 2010. GNU/Linux is the first operating system with official USB 3.0 support.


  1. SuperSpeed - transfer mode at 4.8 Gbit/s. USB 3.0 achieves those speeds with a new plug and cable format, but it is all backward-compatible with USB 2.0 and USB 1.1.

  2. Full-duplex: Devices can send and retrieve data simultaneously.

  3. Support for streaming.

  4. Improved power management - idle, sleep and suspend states.

There is a 127 device limitation per controller.
