The suite of tools include firmware upgrade application, driver installation package, and applications that send transfers to the device. For more information, see Test USB Type-C systems with USB Type-C ConnEx.The MUTT software package contains several tools to be used with MUTT devices. The shield has been designed to work with Arduino as the microcontroller. The USB Type-C Connection Exerciser (USB Type-C ConnEx) is a custom shield that has a four-to-one switch to automate USB Type-C interoperability scenarios. The DR MUTT acts like a SuperMutt when testing host mode of the device under test, but it can also switch to host mode to test the function mode of the device under test. Note The downstream device is a 2.0 device, not a USB 3.0 device. The SuperMUTT Pack simulates USB 3.0 hub behaviors. The device controls the hub and also acts as a downstream device. It is a USB 3.0 hub with a Cypress FX2 device downstream. The SuperMUTT Pack is two devices in one. Note: this device does not support operation at Low Speed. Implements SuperSpeed features such as the bulk streams feature. Note Disconnect any existing power adapters and the cable to the host system when you are changing the jumper on the MUTT Pack.
Super mutt how to#
This image shows how to use the jumper for powering the MUTT pack with an external power adapter: This image shows how to use the jumper for powering the MUTT Pack by the USB bus of the host system: Use the following flow chart to determine how to power the MUTT Pack:ĭo not use the MUTT Pack without the power jumper. In self-powered mode, the MUTT Pack is powered with an external 5V power adapter. In bus-powered mode, the USB bus of the host system powers the MUTT Pack. The MUTT Pack uses a small jumper (see Figure 3) to switch between self-powered and bus-powered modes. The standard A connector is downstream of the embedded hub on the MUTT Pack, and can be used for additional device testing (discussed later in this document). The standard B connector is used to plug the MUTT Pack in to the host system. This can operate as a multi-TT or single-TT high speed hub simulates overcurrent.Įxposes a downstream port that can be turned on or off.Ĭan operate in self-powered or bus-powered modes. The MUTT Pack is a combination of a USB 2.0 hub and an FX2 device that controls the hub and acts as a downstream device.īased on the design on the Cypress Hub and Cypress FX2.

The test tools validate USB host controller software, hardware (including firmware) and any USB hub that is installed between the host controller and the device.
Super mutt drivers#
This package contains several test tools and drivers that let hardware test engineers test interoperability of their USB controller or hub with the Microsoft USB driver stack. To communicate with MUTT devices, you need the MUTT software package. This section provides a brief overview of the different types of MUTT devices, the tests you can run by using the device, and suggests topologies for controller, hub, device, and BIOS/UEFI testing. The Microsoft USB Test Tool (MUTT) is collection of devices for testing interoperability of your USB hardware with the Microsoft USB driver stack.
The manufactures listed in this section sell MUTT hardware boards required to run interoperability tests.
