-	  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.
