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. This paper provides a brief overview of the different types of MUTT hardware and suggests topologies for controller, hub, device, and BIOS/UEFI testing. The paper contains procedural information about how to run the tests, trace events in the USB driver stack, and capture information in the kernel debugger.
This information applies to the following operating systems:
- Windows 8.1
Changes for version 1.9.1
- In version 1.9 and earlier, on some systems, the SuperMutt device enumerated at high speed (when connected to an xHCI controller) after the system resumed from S4. Version 1.9.1 corrects that issue.
Changes for version 1.9
- SuperMUTT loads WinUSB driver by default by reading the MS OS descriptor of the device.
- SuperMUTT with WinUSB supports selective suspend by default.
