 To compile libusb 1.0 using MSVC 9:
 
-- download the pthread.h and sched.h headers from 
+Note: in the text below, (Win32) means "when producing 32 bit binaries" and
+(x64) "when producing 64 bit binaries". This is independent of whether your 
+platform is actually 32 or 64 bit.
+
+- Download the pthread.h and sched.h headers from 
   ftp://sourceware.org/pub/pthreads-win32/prebuilt-dll-2-8-0-release/include/
-  into the msvc directory
+  into the msvc directory.
+
 - (Win32) download pthreadVC2.lib from:
   ftp://sourceware.org/pub/pthreads-win32/prebuilt-dll-2-8-0-release/lib/ 
-  into the msvc directory
-- (Win32) download pthreadVC2.dll from the same link either into your executable
-  destination or copy it into C:\Window\System32 or C:\Window\SysWOW64
-- (x64) follow the "Direct access to the CVS code repository" details on
+  into the msvc directory.
+
+- To run the 32 bit executables, download pthreadVC2.dll from the same link 
+  either into your executable destination or copy it into C:\Window\System32
+  (for 32 bit systems) or C:\Windows\SysWOW64 (for 64 bit systems - yes, this
+  is not a typo: 32 bit DLLs must go to SysWOW64 on 64 bit systems).
+
+- (x64) Follow the "Direct access to the CVS code repository" details on
   http://sourceware.org/pthreads-win32/ and create both a pthreadVC2_x64.lib
-  and pthreadVC2_x64.dll from the latest pthread-win32 source. Then copy 
-  pthreadVC2_x64.lib into the msvc directory and the DLL where relevant.
-- edit config_msvc.h according to your needs (you might want to comment out
-  ENABLE_DEBUG_LOGGING)
-- If you don't have it already, download and install the latest Windows DDK 
+  and pthreadVC2_x64.dll from the latest pthread-win32 source.
+  
+- (x64) Copy pthreadVC2_x64.lib to the msvc directory.
+
+- To run the 64 bit executables, you need to either have pthreadVC2_x64.dll
+  in your executable directory or in C:\Windows\System32 (again, not a typo).
+
+- Edit config_msvc.h according to your needs (you might want to comment out
+  ENABLE_DEBUG_LOGGING).
+  
+- If you haven't done so, download and install the latest Windows DDK 
   (http://www.microsoft.com/downloads/details.aspx?FamilyID=2105564e-1a9a-4bf4-8d74-ec5b52da3d00)
+  
 - In Visual Studio, go to Tools -> Options -> Projects and Solutions ->
-  VC++ directories and change the "Include files" and "Library files" 
-  references to point to the correct DDK paths.
+  VC++ directories and add the following to "Include files":
+  <path of Windows DDK>\inc
+  
+- Also in VC++ directories and add the following to "Library files":
+  <path of Windows DDK>\lib\<target platform>\<arch>
+  Where <targe platform> is one of wxp, wlh (Vista) or win7 and <arch> is
+  one of i386 or amd64, depending on whether Platform is Win32 or x64.
+
+You should now be able to compile the solution.
+
+The default solution is set to produce the static library and statically 
+linked binaries. The DLL is currently built as a standalone project.
