		interfaces defined in include/nuttx/input/kbd_codec.h.  These
		special keys include such things as up/down arrows, home and end
		keys, etc.  If this not defined, only 7-bit print-able and control

	---help---
		Mouse positions are accumumated from X/Y displacements reported by
		the mouse device. This setting provides a scaling value for the X
		displacement.  This is a fixed precision floating point number with
		16 bits of fraction.  So a value of 0x00010000 is 1.0, 0x00018000
		is 1.5, 0x00024000 is 2.25, etc.

		Default: 0x00010000 (1.0)

config HIDMOUSE_YSCALE
	hex "Y scaling factor"
	default 0x00010000
	---help---
		Mouse positions are accumumated from X/Y displacements reported by
		the mouse device. This setting provides a scaling value for the Y
		displacement.  This is a fixed precision floating point number with
		16 bits of fraction.  So a value of 0x00010000 is 1.0, 0x00018000
		is 1.5, 0x00024000 is 2.25, etc.

		New mouse positions will only be reported when the X or Y data changes by these
		thresholds. This trades reduces data rate for some loss in dragging accuracy.
		Default: 12

config HIDMOUSE_THRESHY
	int "Y threshold"
	default 12
	---help---
		New touch positions will only be reported when the X or Y data changes by these
		thresholds. This trades reduces data rate for some loss in dragging accuracy.
		Default: 12

endif

config USBHOST_TRACE
	bool "Enable USB HCD tracing for debug"
	default n
	---help---
		Enables USB tracing for debug.  Only supported for the HCD and,

	---help---
		Number of trace entries to remember.

config USBHOST_TRACE_VERBOSE
	bool "Enable verbose debug trace"
	default n
	---help---
		Enable verbose trace output if supported by the platform.  The
		intent is that if USBHOST_TRACE_VERBOSE is not defined, then only
		errors, warnings, and critical messages would be logged.  If
		USBHOST_TRACE_VERBOSE is defined, then general informative trace
		information would also be included.
