config SYSTEM_USBMSC
	bool "USB mass storage class controls"
	default n
	depends on USBMSC && !KERNEL_BUILD
	---help---

config SYSTEM_USBMSC_NLUNS
	int "Number of LUNs"
	default 1
	---help---
		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
	int "LUN1 Minor Device Number"
	default 0
	---help---
		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
	string "LUN1 Device Path"
	default "/dev/mmcsd0"
	---help---
		The full path to the registered block driver.  Default is
		"/dev/mmcsd0"

config SYSTEM_USBMSC_DEVMINOR2
	int "LUN2 Minor Device Number"
	default 1
	---help---
		The minor device number of the block driver for the second LUN. For
		example, N in /dev/mmcsdN.  Used for registering the block driver.
		Ignored if SYSTEM_USBMSC_NLUNS < 2. Default is one.

config SYSTEM_USBMSC_DEVPATH2
	string "LUN2 Device Path"
	default "/dev/mmcsd1"
	---help---
		The full path to the registered block driver.  Ignored if
		SYSTEM_USBMSC_NLUNS < 2. Default is "/dev/mmcsd1"

config SYSTEM_USBMSC_DEVMINOR3
	int "LUN3 Minor Device Number"
	default 2
	---help---
		The minor device number of the block driver for the third LUN. For
		example, N in /dev/mmcsdN.  Used for registering the block driver.
		Ignored if SYSTEM_USBMSC_NLUNS < 2. Default is two.

config SYSTEM_USBMSC_DEVPATH3
	string "LUN3 Device Path"
	default "/dev/mmcsd2"
	---help---
		The full path to the registered block driver.  Ignored if
		SYSTEM_USBMSC_NLUNS < 2. Default is "/dev/mmcsd2"

config SYSTEM_USBMSC_DEBUGMM
	bool "USB MSC MM Debug"
	default n
	---help---
		Enables some debug tests to check for memory usage and memory leaks.

config SYSTEM_USBMSC_TRACE
	bool "Trace USB activity"
	default n
	depends on (USBDEV_TRACE || DEBUG_USB) && !NSH_BUILTIN_APPS
	---help---
		If this add-on is built as a standalone task and if USB device tracing is
		enabled, then this add-on can be configured to unobtrusively monitor
		USB activity by selecting this option.

if SYSTEM_USBMSC_TRACE

config SYSTEM_USBMSC_TRACEINIT
	bool "USB Trace Initialization"
	default n
	---help---
		If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
		then the add-on code will also manage the USB trace output.  The
		amount of trace output can be controlled this configuration value:
		This setting will show USB initialization events

config SYSTEM_USBMSC_TRACECLASS
	bool "USB Trace Class"
	default n
	---help---
		If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
		then the add-on code will also manage the USB trace output.  The
		amount of trace output can be controlled this configuration value:
		This setting will show USB class driver events

config SYSTEM_USBMSC_TRACETRANSFERS
	bool "USB Trace Transfers"
	default n
	---help---
		If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
		then the add-on code will also manage the USB trace output.  The
		amount of trace output can be controlled this configuration value:
		This setting will show USB data transfer events

config SYSTEM_USBMSC_TRACECONTROLLER
	bool "USB Trace Device Controller Events"
	default n
	---help---
		If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
		then the add-on code will also manage the USB trace output.  The
		amount of trace output can be controlled this configuration value:
		This setting will show USB device controller events

config SYSTEM_USBMSC_TRACEINTERRUPTS
	bool "USB Trace Device Controller Interrupt Events"
	default n
	---help---
		If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
		then the add-on code will also manage the USB trace output.  The
		amount of trace output can be controlled this configuration value:
		This setting will show USB device controller interrupt-related events.

config SYSTEM_USBMSC_CMD_STACKSIZE
	int "Stacksize of msconn and msdis commands"
	default 768
	---help---
		Size of the stack used by the small 'msconn' and 'msdis' command
		applications.  Warning, just because the applications are small,
		the stack usage could still be deep!

config SYSTEM_USBMSC_CMD_PRIORITY
	int "Priority of the msconn and msdis commands"
	default 100
	---help---
		Priority of the small 'msconn' and 'msdis' command applications.

config SYSTEM_USBMSC_DAEMON_STACKSIZE
	int "Stacksize of msconn daemon"
	default 2048
	---help---
		To avoid threading entanglements, the USB MSC class is initialized
		on a daemon thread.  This permits the msconn application to return
		to the NSH command line immediately.  This is the stack used for
		that short-lived USB MSC initialization daemon.

config SYSTEM_USBMSC_DAEMON_PRIORITY
	int "Priority of the msconn daemon"
	default 100
	---help---
		To avoid threading entanglements, the USB MSC class is initialized
		on a daemon thread.  This permits the msconn application to return
		to the NSH command line immediately.  This is the priority used for
		that short-lived USB MSC initialization daemon.
