    Covering the latest trends and topics in USB IP.

    I started working on USB in 1995, starting with the world’s first BIOS that supported USB Keyboards and Mice while at Award Software. After a departure into embedded systems software for real-time operating systems, I returned to USB IP cores and software at inSilicon, one of the leading suppliers of USB IP. In 2002, inSilicon was acquired by Synopsys and I’ve been here since. I also served as Chairman of the USB On-The-Go Working Group for the USB Implementers Forum from 2004-2006.

    I received an M.B.A. from Santa Clara University and an M.S. in Engineering from University of California Irvine, and a B.S. in Engineering from the University of Minnesota. I’m a licensed Professional Engineer in Civil Engineering in the State of California

First USB 3.0 Hub Demo ever

Posted by Eric Huang on October 15th, 2009

At Fall 2009 IDF, Synopsys was the first company ever, in the history of the USB to demonstrate a USB 3.0 Device, Host, and Hub all from one company (that’s us).

In this case, our SuperSpeed USB 3.0 Hub is connected to our USB 3.0 Mass Storage Device, a USB 2.0 Flash Drive, and a USB 1.1 Mouse.   The Host we are using is the USB-IF provided one that is part of the USB 3.0 PDK (Peripheral Developer’s Kit).  It’s the NEC version.

The really short (<90 sec) video can be seen here http://www.synopsys.com/dw/ipdir.php?ds=dwc_usb_3

and it should be embedded below also.

 

The point is that we can demonstrate interoperability of USB 3.0, 2,0, and 1.1 products.  This is essential so that you and your customers can use their 10 year old USB mice and inkjet printers with your new USB 3.0 hard drives and flash drives in the year 2010.

Note:  We are actually using a USB 2.0 Hub chip to provide the 2.0 connection, but we can do this because the USB 3.0 and 2.0 are electrically separate.  We only provide the SuperSpeed USB 3.0 Hub portion.

I should also point out that TI had a (really cool) demonstration of their fully integrated USB 3.0 Hub nearby.  We will post a video of that next week.
