USB next Level : USB 3.0

USB 3.0 is coming to town.... Seems Next level from usb known as USB 3.0 will be favorable for many user, "superspeed" will be the nickname for this technology.
Here's the History....

The USB 1.0 specification was introduced in 1996. It was intended to replace the multitude of connectors at the back of PCs, as well as to simplify software configuration of communication devices. The original USB 1.0 specification had a data transfer rate of 12 Mbit/s.
USB was created by a core group of companies that consisted of Intel, Compaq, Microsoft, Digital, IBM, and Northern Telecom. Intel produced the UHCI host controller and open software stack; Microsoft produced a USB software stack for Windows and co-authored the OHCI host controller specification with National Semiconductor and Compaq; Philips produced early USB-Audio; and TI produced the most widely used hub chips. One of the co-inventors of the USB was Ajay Bhatt, who was later given credit in a television ad for Intel.


The USB 2.0 specification was released in April 2000 and was standardized by the USB-IF at the end of 2001. Hewlett-Packard, Intel, Lucent Technologies (now Alcatel-Lucent following its merger with Alcatel in 2006), Microsoft, NEC, and Philips jointly led the initiative to develop a higher data transfer rate, 480 Mbit/s, than the 1.0 specification of 12 Mbit/s.
The USB 3.0 specification was released on November 17, 2008 by the USB 3.0 Promoter Group. It has a transfer rate of up to 10 times faster than the USB 2.0 version and has been dubbed the SuperSpeed USB.

-A low speed rate of 1.5 Mbit/s is defined by USB 1.0. It is very similar to full speed operation except each bit takes 8 times as long to transmit. It is intended primarily to save cost in low-bandwidth human interface devices (HID) such as keyboards, mice, and joysticks.
The full speed rate of 12 Mbit/s is the basic USB data rate defined by USB 1.1. All USB hubs support full speed.
-A high-speed (USB 2.0) rate of 480 Mbit/s was introduced in 2001. All high-speed devices are capable of falling back to full-speed operation if necessary.
-A SuperSpeed (USB 3.0) rate of 5.0 Gbit/s. The USB 3.0 specification was released by Intel and its partners in August 2008, according to early reports from CNET news. The first USB 3 controller chips were sampled in May 2009 [7] and products using the 3.0 specification are expected to arrive in 2009 or 2010.
