config USB_DUMMY_HCD

	tristate "Dummy HCD (DEVELOPMENT)"

	depends on USB=y || (USB=m && USB_GADGET=m)

	help

	  This host controller driver emulates USB, looping all data transfer

	  requests back to a USB "gadget driver" in the same host.  The host

	  side is the master; the gadget side is the slave.  Gadget drivers

	  can be high, full, or low speed; and they have access to endpoints

	  like those from NET2280, PXA2xx, or SA1100 hardware.



	  This may help in some stages of creating a driver to embed in a

	  Linux device, since it lets you debug several parts of the gadget

	  driver without its hardware or drivers being involved.



	  Since such a gadget side driver needs to interoperate with a host

	  side Linux-USB device driver, this may help to debug both sides

	  of a USB protocol stack.



	  Say "y" to link the driver statically, or "m" to build a

	  dynamically linked module called "dummy_hcd" and force all

	  gadget drivers to also be dynamically linked.



# NOTE:  Please keep dummy_hcd LAST so that "real hardware" appears

# first and will be selected by default.
