MCCI Lab Shifts USB 2.0 High-Speed Testing into High Gear
ITHACA, NEW YORK, October 24, 2001
MCCI®, a leading supplier of Universal Serial Bus (USB) software technology, announced it has been certified as an independent laboratory for testing next-generation USB 2.0 high-speed devices. Until now, most high-speed USB devices were certified through attendance at USB Compliance Workshops (a.k.a. “Plugfests”). Held every few months by the USB Implementers Forum (www.usb.org), these test events are limited in both time and scale, allowing only one high-speed device to be registered per attending engineer.
MCCI, which continues to operate as a USB 2.0 low- and full-speed testing lab, can test a USB 2.0 high-speed product in about a week without requiring the attendance of product engineering staff members. Independent testing in MCCI’s dedicated lab will give developers of high-speed USB devices much faster time-to-market and will ensure that proprietary technologies are not revealed prematurely.
“The three cornerstones of rolling out USB 2.0 are device silicon, software from Microsoft, and test capacity,” said MCCI president Terry Moore. “MCCI’s investment and expertise in testing puts the last piece in place that will accelerate the rollout of high-speed USB products.”
MCCI’s years of experience with USB offers product vendors a unique combination of expert testing and expert problem resolution. MCCI is the only USB test facility whose main business is USB technology development (80% of the company’s business is USB drivers and firmware). According to Terry Moore, MCCI is ready and able to “go down to the transistor level to help a customer solve a compliance problem.”
About USB 2.0
The factors that make USB 2.0 high-speed so promising are its speed, its backward compatibility with previous versions of USB, and its broad industry support. With a maximum transfer rate of 480 mbps, or 60 MB per second, USB 2.0 is 40 times faster than USB 1.1. The higher bandwidth provided through USB 2.0 high-speed supports today's most demanding PC user applications, such as digital image creation and interactive gaming, where multiple high-speed peripherals run simultaneously.
A manufacturer's device must pass compliance testing before being permitted to display the new, trademarked, high-speed USB-IF logo which gives users the confidence that it will correctly operate together with other USB devices, whether low-speed, full-speed, or high-speed. The USB test procedures, as governed by the USB Implementers Forum, checks electrical characteristics, device firmware (if applicable), and general interoperability between the device being tested and other “known-good” devices.
MCCI’s USB 2.0 test lab is operational immediately. The cost for testing a high-speed device for compliance with the USB 2.0 test procedures is $5,000. The cost for testing a full-speed or low-speed device for compliance remains at $1,650.
MCCI staff helped to develop the USB specifications, and chair the USB-IF Device Working Group and the Communication Device Class committee. In addition, MCCI is a leading developer of USB drivers and firmware. MCCI supplies system software to computer device manufacturers, such as cable modems, ADSL adapters, and PDAs. A privately held New York Corporation, MCCI has headquarters in Ithaca NY and offices in Bundang, South Korea (near Seoul).
