The first USB 3.0 product certified
The first USB 3.0 product has been certified, bringing the general IT world one step closer to the next high speed data transfer interface threshold. The USB-IF has certified NEC’s xHCI (Extensible Host Controller Interface) chip.
Jeff Ravencraft, president of the USB-IF said that the certification of the NEC controller signals to the industry the SuperSpeed USB is now a reality. This means that host device manufacturers can build devices displaying the SuperSpeed logo. Peripheral device manufacturers now have incentive to develop USB 3.0 products, since host controller units are officially available.
Through Engadget Ravencraft discussed the projections for USB 3.0, stating that the USB-IF expects end products to be available in early 2010, but it is likely that some manufacturers will push to release products before the end of December.
Ravencraft indicated that some companies would be showcasing USB 3.0 items at upcoming trade shows. A Buffalo external hard drive, an ExpressCard-to-USB 3.0 adapter, and a laptop with an integrated USB 3.0 port will be on display at the Intel Developer Forum later this week.
USB 3.0 has 5 Gbps signalling a 10x increase over USB 2.0. Power usage has been optimised, with no device polling and lower active and idle power requirements. USB 3.0 is backwards compatible with USB 2.0 devices and ports, although the speed will be dependent on that of the host port, or device.
