======================================================================
Component Name    : SniffUSB 2.0 - A USB Sniffer for Windows
======================================================================
Version     : 2.0.0006
Release Date: 02/23/07

1.) Added Common.h that includes defines of NTDEVICENAME, LINKMANE
and other strings shared by driver and application for user-mode I/O
on the driver.

2.) Removed unnecessary call to RtlAnsiUnicodeString in logprint.c,
method MyThreadFunction.

3.) Made small improvement to logging contols:

   Pause Log Button : Temporarily pauses logging.
   Resume Log Button: Starts or resumes logging.
   Close Log Button : Closes the driver's handle on the log file.
                      Can only be done of logging is paused.
   Delete Log Button: Deletes the log file.
                      Can only be done if the driver log file handle
                      is closed.

4.) Added code in ui to detect when driver is installed and started. If
driver is not started, then the buttons are enabled a little differently.

======================================================================
Version     : 2.0.0005
Release Date: 01/14/07

1.) Now do display refresh after Install, Uninstall, Replug and Log
Delete buttons are pressed. These need to be explicitly called because
Build 0004 removed the 1-second automatic update.

2.) Added "Uninstall All" button. This button does Uninstall _AND_ Replug
of all installed UsbSnoop filters.

======================================================================
Version     : 2.0.0004
Release Date: 01/13/07

1.) In FdoHookDispatchInternalIoctl now completly zero newly allocated
RP_STACK_CONTEXT structure.

2.) Added sanity checks to prevent write fault when calling RtlCopyBytes
to copy URB in FdoHookDispatchInternalIoctl.

3.) Made some modifications to the user-mode application. Basically the
refresh mechanism made the tool almost impossible to use if there were
a large number of USB devices.

3.1) Added display refresh control group and interface to enable automatic
display refresh and control refresh interval.

3.2) Made log file group and rearranged controls.

3.3) Made filter control group and rearragned install/uninstall/replug
buttons.

3.4) Added a checkbox to control whether devices that are not present are
listed.

4.) Fixed bug in "Present" device indication. Original implementation
made an incorrect comparison using hardware ID. Revised implementation
makes comparison using instance ID.


======================================================================
Version     : 2.0.0003
Release Date: 01/03/07

Trying to iron out occasional crashes - particularly at Add/Remove
time. Testing with DriverVerifier enabled on usbsnoop.sys on 4-way
SMP machine.

1.) In FilterDispatchPnp and FdoHookDispatchPnp now log additional
information for MinorFunction IRP_MN_QUERY_INTERFACE.

2.) Now use InterlockedExchangePointer to update dispatch table pointer.

3.) Added reference counting on DEVICE_EXTENSION memory. With this in
place it is now concievable that final dereference could occur at
IRQL == DISPATCH_LEVEL. To accomodate this slim possibility final
calls to IoDetachDevice and IoDeleteDevice are made using a WorkItem
to insure they are made at IRQL == PASSIVE_LEVEL.


======================================================================
Version     : 2.0.0002
Release Date: 01/01/07

1.) Changed GUID_SD_FILTER_CONTROL_OBJECT so it will not conflict with
the WDK toaster filter sample GUID.

   WAS       : {41966169-3FD7-4392-AFE4-E6A9D0A92C72}
   CHANGED TO: {9FFF154F-2FE5-4341-9799-BDACF40A90E6}

2.) Integrated SniffUSB MFC application's version resources with defines
in BuildNum.h. Now version number for application and driver can be
updated by simply editing BuildNum.h and rebuilding drivers and then
the application.

3.) Restored Benoit's original logging for IRP_MJ_PNP in FilterDispatchAny.
Now logs these calls as they did in the original:

	IRP_MN_START_DEVICE IRP
	IRP_MN_QUERY_INTERFACE IRP
	IRP_MN_QUERY_CAPABILITIES IRP
	IRP_MN_QUERY_PNP_DEVICE_STATE IRP
	IRP_MN_QUERY_DEVICE_RELATIONS IRP
	IRP_MN_QUERY_REMOVE_DEVICE IRP
	IRP_MN_REMOVE_DEVICE IRP

4.) Restored Benoit's original hook for FdoHookDispatchPnp.


======================================================================
Version     : 2.0.0001
Release Date: 12/27/06

Initial release. Adaptation of Benoit PAPILLAULT's SniffUSB V1.8
to allow it to be built using newer development tools.
