	bool "Enable DMA methods"
	default n
	---help---
		Select this enable DMA-related methods in USB device controller driver
		interface.  These methods include the DMA buffer allocation methods:
		allobuffer() and freebuffer().

		The USB class driver allocates packet I/O buffers for data transfer by
		calling the driver allocbuffer() and freebuffer() methods.  Those methods
		are only available if USBDEV_DMA is defined in the system configuration.

config USBDEV_DMAMEMORY
bool "Board DMA Allocation Hooks"
	default n
	depends on USBDEV_DMA
	---help---
		The USB class driver allocates packet I/O buffers for data transfer by
		calling the driver allocbuffer() and freebuffer() methods.  Those methods
		are only available if USBDEV_DMA is defined in the system configuration.

		If USBDEV_DMAMEMORY is also defined in the NuttX configuration, then
		the driver implementations of the allocbuffer() and freebuffer()
		methods may use board-specific usbdev_dma_alloc() and usbdev_dma_free().
		If USBDEV_DMA and USBDEV_DMAMEMORY are both defined, then the board-
		specific logic must provide the functions usbdev_dma_alloc() and
		usbdev_dma_free(): usbdev_dma_alloc() will allocate DMA-capable
		memory of the specified size; usbdev_dma_free() is the corresponding
		function that will be called to free the DMA-capable memory.

config ARCH_USBDEV_STALLQUEUE
	bool
	default n
	---help---
		This option is set by the USB device controller driver (DCD)
		selection.  These selection means that the DCD can support
		queuing of stall requests.  By this, it is meant that, (1) the
		stall is not sent until all write requests preceding the stall
		request are sent, (2) the stall is sent, and then after the
		stall is cleared, (3) all write requests queued after the stall
		are sent.

		If the driver does not support this feature, that the class drivers
		will enable some hokey and inefficient delay logic to workaround
		the lack of queuing.

		specific trace events.  These arrays of strings (and the type struct
