Adoption of the SuperSpeed USB interface is falling short of expectations, NEC said in March it expected to sell 20 million USB 3.0 controllers this year but market research firm In-Stat estimates only 14 million USB 3.0 controllers shipped this year. As many as 1.7 billion devices are expected to ship with USB 3.0 in 2014, but USB 2.0 will still command the brunt of the USB market and even USB 1.1 devices will still be shipping in volumes of about 500 million units in 2014.
Intel is expected to roll USB 3.0 support into chip sets for its Sandy Bridge processors debuting in 2011. However, the company hasn't confirmed its plans yet.
Even in 2014, USB 2.0 will still command the brunt of the USB market, said In-Stat. In addition, USB 1.1 devices will still be shipping in volumes of about 500 million units in 2014, it said.
Nevertheless, USB 3.0 is poised to make in-roads in a wide variety of systems according to the report. By 2014, USB 3.0 could be used in 225 million flash drives, seven million set-top boxes and 40 percent of all digital media players, the company forecasted.
