Also known as SuperSpeed USB, USB 3.0 from the USB-IF (USB Implementer’s Forum) brings a 5 Gb/s signaling rate to USB, which is a 10X increase in performance from Hi-Speed USB. (Wonder what the next moniker will be...?)
As you might expect, USB 3.0 is backward compatible with existing USB 2.0 infrastructure. According to the USB-IF, SuperSpeed USB also has a “Sync-N-Go technology” to minimize wait time, and is optimized for power efficiency (due to the lack of device polling as well as lower active and idle power requirements).
You need to know a lot about USB 3.0 in order to test it. Right now, compliance testing is available at a number of independent test labs (who stand ready to test USB 3.0 peripherals, peripheral silicon, and end user hosts).
(A list of independent test labs can be found here.)
You can review the USB-IF compliance test procedure and checklists on the USB-IF site, or you can review a design article: "Navigating successful USB 3.0 compliance" by Tom Rossi and Fred Rastgar at InStryde LLC. They give you the background on the spec and what you should “know before you go” to the independent test labs to save you both time and money.
