Debug USB bidi extension file RRS feed

  • Question

  • How to debug USB Bidi extension file..????

    I tried:

    Key Name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print

    Value Name: EnableJavaScriptDebugging

    Type: DWORD

    Value: 1

    1. Attach your debugger to the hosting process. For USB Bidi JavaScript, this is spoolsv.exe.

    2. Set the debugger to script debugging mode.

    3. Select “Break All” (Ctrl + Alt + Break) to break into the process the next time a script runs.

    4. Run the scenario to reproduce your issue.

    5. Once the debugger breaks into a JavaScript function, set any necessary breakpoints and step through the code.

    but it didn't work for me. I didn't get expected output. 

    Please help..

    Thank you..
