MANHASSET, NY -- ASMedia, a leading Taiwanese supplier of xHCI-compatible host controllers, has leveraged MCCI’s USB 3.0 host system software stack for Windows and onsite support to achieve USB-IF SuperSpeed logo certification for its xHCI 1.0-compatible ASM1042 USB 3.0 host controller.
To meet the software requirements of the test, MCCI provided its Windows USB host stack, which is fully compatible with the Microsoft native USB host stack. MCCI worked closely with ASMedia for verification and later for testing at the USB-IF Super-Speed Platform Interoperability Lab in Oregon, providing onsite support with engineers from MCCI’s development center in Ithaca, NY.
“It’s impossible to verify the correct function of an embedded stack without a strategy that involves deploying the embedded stack in mass production into the Windows ecosystem. MCCI is the only software vendor who has succeeded in delivering a Windows stack, and the only embedded software vendor with a tested stack that can be deployed anywhere,” said Terry Moore, CEO, MCCI.

MCCI’s recently announced TrueTask USB 2.0/3.0 platform using the same host stack core that is used by the MCCI Windows stack.
In order to pass xHCI certification, host controllers and their associated software stacks must show compatibility with a wide range of carefully selected devices and their associated drivers and applications. Testing includes not only simple demonstration of performance, but operation in conjunction with other devices and stable performance while executing a variety of Windows suspend, hibernate and reboot procedures.
“Because TrueTask USB is based on the same core technology without source code changes, the testing and verification done on MCCI’s USB core driver (USBD), hub drivers, and xHCI low-level driver are directly applicable to any embedded system," added Moore.
MCCI develops embedded USB software for the high-volume personal computer, embedded and consumer devices, including Qualcomm, Intel, Apple and Sony and has delivered one billion products with MCCI technology.
Earlier this year MCCI announced that its full line of driver products have been tested and validated for Windows 8 Customer Preview. Windows 8 was pre-releasd in March and is to be released next week (Oct.26).
