+^^^^^^^^^^^^^^^^^^
+
+ This logic adds a NXH command to control a USB composite device. The only
+ supported composite is CDC/ACM serial with a USB mass storage device.
+
+ Required overall configuration:
+
+ CONFIG_USBDEV=y - USB device support
+ CONFIG_USBDEV_COMPOSITE=y - USB composite device support
+ CONFIG_COMPOSITE_IAD=y - Interface associate descriptor needed
+
+ CONFIG_CDCACM=y - USB CDC/ACM serial device support
+ CONFIG_CDCACM_COMPOSITE=y - USB CDC/ACM serial composite device support
+ CONFIG_CDCACM_IFNOBASE=0 - CDC/ACM interfaces start with number 0
+ CONFIG_CDCACM_STRBASE=4 - Base of string numbers (not really needed)
+ CONFIG_CDCACM_EPINTIN=1 - Endpoint numbers must be unique
+ CONFIG_CDCACM_EPBULKIN=2
+ CONFIG_CDCACM_EPBULKOUT=3
+
+ CONFIG_USBMSC - USB mass storage device support
+ CONFIG_USBMSC_COMPOSITE=y - USB mass storage composite device support
+ CONFIG_USBMSC_IFNOBASE=2 - USB mass storage interfaces start with number 2
+ CONFIG_USBMSC_STRBASE=4 - Base of string numbers (needed)
+ CONFIG_USBMSC_EPBULKOUT=4 - Endpoint numbers must be unique
+ CONFIG_USBMSC_EPBULKIN=5
+
+ CONFIG_NSH_BUILTIN_APPS
+ This add-on can be built as two NSH "built-in" commands if this option
+ is selected: 'conn' will connect the USB composite device; 'msdis'
+ will disconnect the USB composite device.
+
+ Configuration options unique to this add-on:
+
+ CONFIG_SYSTEM_COMPOSITE_DEBUGMM
+ Enables some debug tests to check for memory usage and memory leaks.
+
+ CONFIG_SYSTEM_COMPOSITE_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_COMPOSITE_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_COMPOSITE_DEVPATH1
+ The full path to the registered block driver. Default is "/dev/mmcsd0"
+ CONFIG_SYSTEM_COMPOSITE_DEVMINOR2 and CONFIG_SYSTEM_COMPOSITE_DEVPATH2
+ Similar parameters that would have to be provided if CONFIG_SYSTEM_COMPOSITE_NLUNS
+ is 2 or 3. No defaults.
+ CONFIG_SYSTEM_COMPOSITE_DEVMINOR3 and CONFIG_SYSTEM_COMPOSITE_DEVPATH2
+ Similar parameters that would have to be provided if CONFIG_SYSTEM_COMPOSITE_NLUNS
+ is 3. No defaults.
+
+ CONFIG_SYSTEM_COMPOSITE_TTYUSB - The minor number of the USB serial device.
+ Default is zero (corresponding to /dev/ttyUSB0 or /dev/ttyACM0). Default is zero.
+ CCONFIG_SYSTEM_COMPOSITE_SERDEV - The string corresponding to
+ CONFIG_SYSTEM_COMPOSITE_TTYUSB. The default is "/dev/ttyUSB0" (for the PL2303
+ emulation) or "/dev/ttyACM0" (for the CDC/ACM serial device).
+ CONFIG_SYSTEM_COMPOSITE_BUFSIZE - The size of the serial I/O buffer in
+ bytes. Default 256 bytes.
+
+ If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
+ the add-on code will also manage the USB trace output. The amount of trace output
+ can be controlled using:
+
+ CONFIG_SYSTEM_COMPOSITE_TRACEINIT
+ Show initialization events
+ CONFIG_SYSTEM_COMPOSITE_TRACECLASS
+ Show class driver events
+ CONFIG_SYSTEM_COMPOSITE_TRACETRANSFERS
+ Show data transfer events
+ CONFIG_SYSTEM_COMPOSITE_TRACECONTROLLER
+ Show controller events
+ CONFIG_SYSTEM_COMPOSITE_TRACEINTERRUPTS
+ Show interrupt-related events.
