-  The trace facility works like this:
-  When enabled, USB events that occur in either the USB device driver or in the USB class driver are logged.
-  These events are described in include/nuttx/usb/usbdev_trace.h.
-  The logged events are identified by a set of event IDs:

-  The logged data itself may go to either (1) an internal circular buffer, or (2) may be provided on the console.
-  If CONFIG_USBDEV_TRACE is defined, then the trace data will go to the circular buffer.
-  The size of the circular buffer is determined by CONFIG_USBDEV_TRACE_NRECORDS.
-  Otherwise, the trace data goes to console.

                            USB Device Tracing Controls.
+  The NuttX USB device subsystem supports a fairly sophisticated tracing facility.
+  The basic trace cabability is controlled by these NuttX configuration settings:
+
                            
+
                              
+  
                            • CONFIG_USBDEV_TRACE: Enables USB tracing
                              • 
+  
                            • CONFIG_USBDEV_TRACE_NRECORDS: Number of trace entries to remember
                              • 
+
                            
+
                            Trace IDs.
+  The trace facility works like this:
+  When enabled, USB events that occur in either the USB device driver or in the USB class driver are logged.
+  These events are described in include/nuttx/usb/usbdev_trace.h.
+  The logged events are identified by a set of event IDs:
+
                            
+

                            1. 8-bits of the trace ID (values associated with the above)

+  
                            2. 8-bits of additional trace ID data, and

                            3. 16-bits of additonal data.

+
                            8-bit Trace Data
+  The 8-bit trace data depends on the specific event ID.  As examples,
+
                            
+
                              
+  
                            • 
+    For the USB serial and mass storage class, the 8-bit event data is provided in include/nuttx/usb/usbdev_trace.h. 
+  
                              • 
+  
                            • 
+    For the USB device driver, that 8-bit event data is provided within the USB device driver itself.
+    So, for example, the 8-bit event data for the LPC1768 USB device driver is found in arch/arm/src/lpc17xx/lpc17_usbdev.c.
+  
                              • 
+
                            
+
                            16-bit Trace Data.
+  The 16-bit trace data provided additional context data relevant to the specific logged event.
+
                            
+
                            Trace Control Interfaces.
+  Logging of each of these kinds events can be enabled or disabled using the interfaces described in include/nuttx/usb/usbdev_trace.h.
+
                            
+
                            Enabling USB Device Tracing.
+  USB device tracing will be configured if CONFIG_USBDEV and either of the following are set in the NuttX configuration file:
+
                            
+
                              
+  
                            • CONFIG_USBDEV_TRACE, or
                              • 
+  
                            • CONFIG_DEBUG and CONFIG_DEBUG_USB
                              • 
+
                            
+
                            Log Data Sink.
+  The logged data itself may go to either (1) an internal circular buffer, or (2) may be provided on the console.
+  If CONFIG_USBDEV_TRACE is defined, then the trace data will go to the circular buffer.
+  The size of the circular buffer is determined by CONFIG_USBDEV_TRACE_NRECORDS.
+  Otherwise, the trace data goes to console.
+
                            
+
                            Example.
+  Here is an example of USB trace output using apps/examples/usbserial for an LPC1768 platform with the following NuttX configuration settings:
+

-BUILDING THE R8C/M16C/M32C GNU TOOLCHAIN USING BUILDROOT
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-NOTE:  See the toolchain issues above -- you may not want to waste your time.
-
-1. CD to the correct directory.
-
-   Change to the directory just above the NuttX installation.  If  is
-   where NuttX is installed, then cd to /..
-
-2. Get and Install the buildroot Module
-
-   a. Using a release tarball:
-
-     cd /..
-     Download the appropriate buildroot package.
-     unpack the buildroot package
-     rename the directory to buildroot
-
-   b. Using SVN
-   
-     Check out the misc/buildroot module. SVN checkout instructions:
-
-        svn checkout svn://svn.code.sf.net/p/nuttx/code/trunk/buildroot buildroot
-
-   Make the archive directory:
-  
-     mkdir archive
-
-   The /../buildroot is where the toolchain is built;
-   The /../archive directory is where toolchain sources will be downloaded.
-
-3. Make sure that NuttX is configured
-
-     cd /tools
-     ./configure.sh 
-     
-4. Configure and Make the buildroot
-
-     cd buildroot
-     cp configs/m32c-defconfig-4.2.4 .config
-     make oldconfig
-     make
-
-   This will download the large source packages for the toolchain and build the toolchain.
-   The resulting binaries will be under buildroot/build_m32c.  There will also be a
-   large build directory called toolchain_build_m32c; this directory can be removed once
-   the build completes successfully.
-
-Cygwin GCC BUILD NOTES
-^^^^^^^^^^^^^^^^^^^^^^
-   On Cygwin, the buildroot 'make' command will fail with an error like:
-
-   "...
-      build/genchecksum cc1-dummy > cc1-checksum.c
-      opening cc1-dummy: No such file or directory
-   ..."
-
-   This is caused because on Cygwin, host executables will be generated with the extension .exe
-   and, apparently, the make variable "exeext" is set incorrectly.  A work around after the
-   above occurs is:
-
-      cd toolchain_build_m32c/gcc-4.2.4-initial/gcc	# Go to the directory where error occurred
-      mv cc1-dummy.exe cc1-dummy			# Rename the executable without .exe
-      rm cc1-checksum.c					# Get rid of the bad generated file
-
-   Then resume the buildroot make:
-
-      cd -						# Back to the buildroot make directory
-      make						# Restart the build
-
-   GCC is built twice.  First a initial, "bootstap" GCC is produced in
-   toolchain_build_m32c/gcc-4.2.4-initial, then the final GCC is produced in
-   toolchain_build_m32c/gcc-4.2.4-final.  The above error will occur twice:  Once for
-   the intial GCC build (see above) and once for the final GCC build. For the final GCC
-   build, the workaround is the same except that the directory will be
-   toolchain_build_m32c/gcc-4.2.4-final/gcc.
