	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.
