-^^^^^^^^^^^^^^^
-
-  This very simple example shows how a USB CDC/ACM serial can be dynamically
-  connected and disconnected from a host.  This example can only be used as
-  an NSH built-int command.  If built-in, then two new NSH commands will be
-  supported:
-
-    1. sercon - Connect the CDC/ACM serial device
-    2. serdis - Disconnect the CDC/ACM serial device
-
-  Configuration prequisites (not complete):
-
-    CONFIG_USBDEV=y                 : USB device support must be enabled
-    CONFIG_CDCACM=y                 : The CDC/ACM driver must be built
-    CONFIG_NSH_BUILTIN_APPS         : NSH built-in application support must be enabled
-
-  Configuration options specific to this example:
-
-    CONFIG_EXAMPLES_CDCACM_DEVMINOR : The minor number of the CDC/ACM device.
-                                    : i.e., the 'x' in /dev/ttyACMx
-
-  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB, or
-  CONFIG_USBDEV_TRACE), then the example code will also initialize the USB trace
-  output.  The amount of trace output can be controlled using:
-
-  CONFIG_EXAMPLES_CDCACM_TRACEINIT
-    Show initialization events
-  CONFIG_EXAMPLES_CDCACM_TRACECLASS
-    Show class driver events
-  CONFIG_EXAMPLES_CDCACM_TRACETRANSFERS
-    Show data transfer events
-  CONFIG_EXAMPLES_CDCACM_TRACECONTROLLER
-    Show controller events
-  CONFIG_EXAMPLES_CDCACM_TRACEINTERRUPTS
-    Show interrupt-related events.
-
-  Note:  This example is only enables or disable USB CDC/ACM via the NSH
-  'sercon' and 'serdis' command.  It will enable and disable tracing per
-  the settings before enabling and after disabling the CDC/ACM device. It
-  will not, however, monitor buffered trace data in the interim.  If
-  CONFIG_USBDEV_TRACE is defined (and the debug options are not), other
-  application logic will need to monitor the buffered trace data.

+system/usbmsc
+^^^^^^^^^^^^^^^
+
+  This add-on registers a block device driver, then exports the block
+  the device using the USB storage class driver.  In order to use this
+  add-on, your board-specific logic must provide the function:
+
+    void usbmsc_archinitialize(void);
+
+  This function will be called by the system/usbmsc in order to
+  do the actual registration of the block device drivers.  For examples
+  of the implementation of usbmsc_archinitialize() see
+  configs/mcu123-lpc124x/src/up_usbmsc.c or
+  configs/stm3210e-eval/src/usbmsc.c
+
+  Configuration options:
+
+  CONFIG_NSH_BUILTIN_APPS
+    This add-on can be built as two NSH "built-in" commands if this option
+    is selected: 'msconn' will connect the USB mass storage device; 'msdis'
+    will disconnect the USB storage device.
+  CONFIG_SYSTEM_USBMSC_NLUNS
+    Defines the number of logical units (LUNs) exported by the USB storage
+    driver.  Each LUN corresponds to one exported block driver (or partition
+    of a block driver).  May be 1, 2, or 3.  Default is 1.
+  CONFIG_SYSTEM_USBMSC_DEVMINOR1
+    The minor device number of the block driver for the first LUN. For
+    example, N in /dev/mmcsdN.  Used for registering the block driver. Default
+    is zero.
+  CONFIG_SYSTEM_USBMSC_DEVPATH1
+    The full path to the registered block driver.  Default is "/dev/mmcsd0"
+  CONFIG_SYSTEM_USBMSC_DEVMINOR2 and CONFIG_SYSTEM_USBMSC_DEVPATH2
+    Similar parameters that would have to be provided if CONFIG_SYSTEM_USBMSC_NLUNS
+    is 2 or 3.  No defaults.
+  CONFIG_SYSTEM_USBMSC_DEVMINOR3 and CONFIG_SYSTEM_USBMSC_DEVPATH3
+    Similar parameters that would have to be provided if CONFIG_SYSTEM_USBMSC_NLUNS
+    is 3.  No defaults.
+  CONFIG_SYSTEM_USBMSC_DEBUGMM
+    Enables some debug tests to check for memory usage and memory leaks.
+
+  If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
+  the code will also manage the USB trace output.  The amount of trace output
+  can be controlled using:
+
+  CONFIG_SYSTEM_USBMSC_TRACEINIT
+    Show initialization events
+  CONFIG_SYSTEM_USBMSC_TRACECLASS
+    Show class driver events
+  CONFIG_SYSTEM_USBMSC_TRACETRANSFERS
+    Show data transfer events
+  CONFIG_SYSTEM_USBMSC_TRACECONTROLLER
+    Show controller events
+  CONFIG_SYSTEM_USBMSC_TRACEINTERRUPTS
+    Show interrupt-related events.
+
+  Error results are always shown in the trace output
+
+  NOTE 1: When built as an NSH add-on command (CONFIG_NSH_BUILTIN_APPS=y),
+  Caution should be used to assure that the SD drive (or other storage device) is
+  not in use when the USB storage device is configured.  Specifically, the SD
+  driver should be unmounted like:
+
+  nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
+  ...
+  nsh> umount /mnd/sdcard                    # Unmount before connecting USB!!!
+  nsh> msconn                                # Connect the USB storage device
+  ...
+  nsh> msdis                                 # Disconnect USB storate device
+  nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
+
+  Failure to do this could result in corruption of the SD card format.
+
+  NOTE 2: This add-on used internal USB device driver interfaces.  As such,
+  it relies on internal OS interfaces that are not normally available to a
+  user-space program.  As a result, this add-on cannot be used if a
+  NuttX is built as a protected, supervisor kernel (CONFIG_NUTTX_KERNEL).
