About

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

Lower Power USB

Posted by Eric Huang on 20th December 2007

As I finish my shopping, I’ve noticed just about everything seems to use USB, or at least the gifts I have purchased. The iPod iTouch, Canon DSC, Bluetooth headset. The only thing I haven’t found is a Foot Spa powered by USB. If anyone has seen one, let me know.

My Product Ideas (for you to steal):

1) USB Power port in the car – lower voltage is just right…
2) USB Foot Spa – Imagine clicking a mouse to turn up the bubbles?
3) Programmable Talking Fortune Teller – Fortunes uploaded daily via USB (WiFi too expensive)
4) USB powered hair clippers, okay dumb idea.
5) Lower Power USB (not my idea)

The USB-IF formalized an ECN on Link Power Management that introduces a new sleep mode in USB. The L1 Sleep Mode reduces suspend and resume times by 1000 times, so that the PHY and Link must suspend or wakeup in micro 10 microseconds rather than 3ms. Also, per port power control and supplying power to down stream peripherals is now actively manageable. Go to www.usb.org and download the zip file with the spec to learn more.

For more low power from Synopsys, go to our Low Power Blog. I have no idea if it’s any good (I’m trying to pick an on-line fight here), but he’s got a huge following so that must mean something.

Happy Holidays and a Happy New Year

In addition to a Wish for Wireless USB products, I like toys. PC Magazine has 10 USB powered gift ideas . I like the Solar Powered Bluetooth car-kit for use in your card (it charges via USB also). I figure, if I leave this on the dash of my car, it will charge enough for my drive home and drive to work each day. I also love the USB Microscope. Mattel had one like this years ago, and I’m glad to see there is one again. This is one toy I might get for my kids. But they are spoiled enough already.

Wireless USB Gifts for 2007

Posted by Eric Huang on 5th December 2007

Looks like the IOGear and other Certified Wireless USB products are available now on Amazon. I just received a Google Alert telling me that Tom’ Hardware Review Holiday Gift Giving Guide recommends the IOGear product. My dad has been bugging me for a USB 2.0 Hub, but I think this is better. The USB 2.0 Hub works great, but if I give him the Wireless Version, all the peripherals stay plugged into the Wireless Hub and he just plugs a USB Stick (like a flash drive) into the Laptop and he’s done. One less cable.
I looked under my desk at home the other day, and with the 8 Power Cables, 6 USB cables, 2 1394 cables, and 2 speaker cables. At least I could reduce the 8 USB cables to 1 with Wireless.
