Running the DSF Sample Devices

To run the DSF sample devices on a target system after installing the DSF runtime, you must first create a simulated USB 2.0 EHCI controller. To create a controller, open a Command Prompt window, navigate to the \Program Files\dsf\softehci folder, and run softehcicfg /install.

You must wait for the controller to enumerate before running any of the sample devices. You can check Device Manager to see when the controller has appeared or wait for the audio confirmation tone. The controller will be displayed as "Microsoft USB 2.0 Host Controller Simulator".

The following topics describe how to run the DSF samples:
