In the real world, it's not enough for a USB device or hub manufacturer to simply prove that it has correctly followed the USB specification. You can never be sure what revision level of machines or subtle differences a device will have to contend with in the field. The bottom line is that you don't want to spend all of your time debugging other manufacturers' designs. But you do need to know what's out there in order to defend your own design against potential failures in the hands of real-world users.
NTS knows from our experience that compliance does not always guarantee compatibility with other products, and you want to make sure your product is compatible with various USB-compliant products on the market today. To address these issues, NTS has developed the NTS USB Golden Suite that goes beyond the standard USB-IF certification. It answers the questions regarding whose fault is it, how bad is it out there, will my product perform as expected, and will it be a success or a failure.
The NTS USB Golden Suite focuses on real-world testing of your USB product with a variety of platforms, peripherals and operating systems. The testing covers all USB chipsets using up to 200 USB devices and peripherals, along with supporting operating systems including Apple Mac OS X®, Microsoft Windows 98® , Microsoft Windows 2000®, Microsoft Windows XP®, Microsoft Windows Vista®, Microsoft Windows Server 2003®. NTS's USB Golden Suite test procedures consist of five (5) major coverage areas: Installation Testing; Device Functionality Testing; Interoperability Testing; Hot Detach/Reattach Functionality Testing; and Power Management Functionality Testing. Make sure your product is ready for the market before you release it!
In addition to the USB Golden Suite, NTS has also developing USB test suites for Macintosh/MacOS peripherals, Microsoft Windows CE systems and peripherals, and Linux systems and peripherals
NTS has the expertise to assist you in all of your USB testing requirements including Microsoft WHQL USB testing of devices and hubs, and USB Embedded Host and USB OTG testing.
