The Microsoft USB Test Tool (MUTT) software package contains test tools for hardware test engineers to test interoperability of their USB controller or hub with the Microsoft USB driver stack. The package contains two downloads: the tools package and a readme document.

The tools package contains several tools that perform stress and transfer tests (including power transitions) and SuperSpeed tests. The package also contains the USB Hardware Verifier tool (see this blog post). The document gives you a brief overview of the types of MUTT hardware, provides step-by-step guidance about various tests you should run, and suggests topologies for controller, hub, device, and BIOS/UEFI testing. 
Download the tools package and documentation from MSDN.
