Select in the list of the left side the driver class which you want trace. You can make a right click on a driver class to re-enum this class.

In the middle, all hooked devices are listed. For each hooked device you can specify the trace options.

Since 'UpperFilters' and 'LowerFilters' are only supported in Windows 2000 and above, RequestTrace is only working on 32 and AMD64 bit versions of Windows Vista, Windows XP and Windows 2000. Windows 98 doesn't work, because I'm using an function which is not available in Windows 98.

All output is visible in every debugger, like DebugView, SoftIce or WinDbg.

Please note, this is a not a final version, please run this only on your debug machine with a backup. If you find bugs, encounter problems or have hints, please send me a mail. Since I'm still adding some new irp's, send a mail to request the latest version.
