    Hi All
    Is there any equivalent of Enabling verbose Debug Tracing in usbstor.sys
    similar to usbaudio.sys or usbhub.sys in checked builds ?
    ie ed USBHUB!USBH_Debug_Trace_Level 3
    TIA

  2. 1) Get checked build usbstor.sys
    2) Set
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\USBSTOR\Parameters\DebugLevel
    REG_DWORD 3
    3) Set
    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\USBSTOR\Parameters\DebugFlags
    REG_DWORD 0xFFFFFFFF

    You can also set these values directly using a kernel debugger. These values
    are stored in a gloabl structure:

    kd> dt usbstor!USBSTOR_DriverGlobals

    Let me if this works. I will get this info added to our KB
    article:http://support.microsoft.com/default.aspx?scid=kb;en-us;314743
