LONDON — A clutch of companies demonstrated interoperable prototype hosts and devices for the upcoming SuperSpeed USB at this week's USB Implementers Forum in Tokyo, Japan.

Companies including Fresco Logic, Fujitsu Microelectronics Limited, LucidPort Technology, Inc. and NEC Electronics Corporation showcased interoperable PC hosts and peripheral devices using prototype software from Intel Corporation to seamlessly transport SuperSpeed USB traffic.

The SuperSpeed USB 3.0 interface, released last November, runs at up to 5 Gbits/s and can deliver as much as 300 Mbytes/second of data at the application layer.

"The fact that companies are already demonstrating interoperable SuperSpeed USB solutions underscores the intense interest and market need for this technology," said Jeff Ravencraft, USB-IF president and chairman.

'The combination of market-leading data transfer speeds, improved power efficiency and backward compatibility with the billions of USB devices has resulted in excitement from silicon vendors, electronics manufacturers and consumers alike," Ravencraft added in a statement.

The demonstrations included a Fresco Logic prototype PC host working with a mass storage device from Fujitsu. In another demonstration, NEC Electronics Corporation featured a PC host transferring data to a mass storage device from LucidPort.

As already highlighted Texas Instruments demonstrated a 5Gbit/s transceiver test chip at the event.

SuperSpeed USB products are expected to be available in early 2010.
