How to Enable Windows* Software Trace Preprocessor Logging Under S0 State


Install & Setup



To capture Windows* Software Trace (WPP) log for USB 3.0 device under S0 operation, follow these steps:
  1. Go to the driver-installed folder and folder \Debug_Scripts.
  2. Open readme.txt for instructions to use script files.
  3. Open Command Prompt with Run as Administrator privileges, and go to folder location in step one.
  4. Run start_WPP_logman.bat temp; this creates temp.etl file and starts logging driver messages.
  5. Connect a USB 3.0 device, check enumeration in Device Manager, and copy a file to the device.
  6. Run Stop_WPP_logman.bat. These WPP log files are encoded, and only Intel can decode.

This tool is more useful for troubleshooting USB 3.0 devices. For debugging an issue, use third-party tools.
