-<p><b>USB Device Tracing Controls</b>.

-  The NuttX USB device subsystem supports a fairly sophisticated tracing facility.

-  The basic trace cabability is controlled by these NuttX configuration settings:

-</p>

-<ul>

-  <li><code>CONFIG_USBDEV_TRACE</code>: Enables USB tracing</li>

-  <li><code>CONFIG_USBDEV_TRACE_NRECORDS</code>: Number of trace entries to remember</li>

-</ul>

-<p><b>Trace IDs</b>.

-  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 <code>include/nuttx/usb/usbdev_trace.h</code>.

-  The logged events are identified by a set of event IDs:

-</p>

-<ul><table>

-  <tr>

-    <td><code>TRACE_INIT_ID</code></td>

-    <td>Initialization events</td>

-  </tr>

-<p><b>Logged Events</b>.

-  Each logged event is 32-bits in size and includes

-</p>

-<ol>

-  <li>8-bits of the trace ID (values associated with the above)</li>

-  <li>8-bits of additional trace ID data, and</li>

-  <li>16-bits of additonal data.</li>

-</ol>

-<p><b>8-bit Trace Data</b>

-  The 8-bit trace data depends on the specific event ID.  As examples,

-</p>

-<ul>

-  <li>

-    For the USB serial and mass storage class, the 8-bit event data is provided in <code>include/nuttx/usb/usbdev_trace.h</code>. 

-  </li>

-  <li>

-    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 <code>arch/arm/src/lpc17xx/lpc17_usbdev.c</code>.

-  </li>

-</ul>

-<p><b>16-bit Trace Data</b>.

-  The 16-bit trace data provided additional context data relevant to the specific logged event.

-</p>

-<p><b>Trace Control Interfaces</b>.

-  Logging of each of these kinds events can be enabled or disabled using the interfaces described in <code>include/nuttx/usb/usbdev_trace.h</code>.

-</p>

-<p><b>Enabling USB Device Tracing</b>.

-  USB device tracing will be configured if <code>CONFIG_USBDEV</code> and either of the following are set in the NuttX configuration file:

-<p><b>Log Data Sink</b>.

-  The logged data itself may go to either (1) an internal circular buffer, or (2) may be provided on the console.

-  If <code>CONFIG_USBDEV_TRACE</code> is defined, then the trace data will go to the circular buffer.

-  The size of the circular buffer is determined by <code>CONFIG_USBDEV_TRACE_NRECORDS</code>.

-  Otherwise, the trace data goes to console.

-<p><b>Example</b>.

-  Here is an example of USB trace output using <code>apps/examples/usbserial</code> for an LPC1768 platform with the following NuttX configuration settings:

+<p><b>USB Device Tracing Controls</b>.
+  The NuttX USB device subsystem supports a fairly sophisticated tracing facility.
+  The basic trace cabability is controlled by these NuttX configuration settings:
+</p>
+<ul>
+  <li><code>CONFIG_USBDEV_TRACE</code>: Enables USB tracing</li>
+  <li><code>CONFIG_USBDEV_TRACE_NRECORDS</code>: Number of trace entries to remember</li>
+</ul>
+<p><b>Trace IDs</b>.
+  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 <code>include/nuttx/usb/usbdev_trace.h</code>.
+  The logged events are identified by a set of event IDs:
+</p>
+<ul><table>
+  <tr>
+    <td><code>TRACE_INIT_ID</code></td>
+    <td>Initialization events</td>
+  </tr>
+  <tr>
+    <td><code>TRACE_EP_ID</code></td>

+<p><b>Logged Events</b>.
+  Each logged event is 32-bits in size and includes
+</p>
+<ol>
+  <li>8-bits of the trace ID (values associated with the above)</li>
+  <li>8-bits of additional trace ID data, and</li>
+  <li>16-bits of additonal data.</li>
+</ol>
+<p><b>8-bit Trace Data</b>
+  The 8-bit trace data depends on the specific event ID.  As examples,
+</p>
+<ul>
+  <li>
+    For the USB serial and mass storage class, the 8-bit event data is provided in <code>include/nuttx/usb/usbdev_trace.h</code>. 
+  </li>
+  <li>
+    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 <code>arch/arm/src/lpc17xx/lpc17_usbdev.c</code>.
+  </li>
+</ul>
+<p><b>16-bit Trace Data</b>.
+  The 16-bit trace data provided additional context data relevant to the specific logged event.
+</p>
+<p><b>Trace Control Interfaces</b>.
+  Logging of each of these kinds events can be enabled or disabled using the interfaces described in <code>include/nuttx/usb/usbdev_trace.h</code>.
+</p>
+<p><b>Enabling USB Device Tracing</b>.
+  USB device tracing will be configured if <code>CONFIG_USBDEV</code> and either of the following are set in the NuttX configuration file:
+</p>
+<ul>
+  <li><code>CONFIG_USBDEV_TRACE</code>, or</li>
+  <li><code>CONFIG_DEBUG and CONFIG_DEBUG_USB</code></li>
+</ul>
+<p><b>Log Data Sink</b>.
+  The logged data itself may go to either (1) an internal circular buffer, or (2) may be provided on the console.
+  If <code>CONFIG_USBDEV_TRACE</code> is defined, then the trace data will go to the circular buffer.
+  The size of the circular buffer is determined by <code>CONFIG_USBDEV_TRACE_NRECORDS</code>.
+  Otherwise, the trace data goes to console.
+<p>
+<p><b>Example</b>.
+  Here is an example of USB trace output using <code>apps/examples/usbserial</code> for an LPC1768 platform with the following NuttX configuration settings:
