I added the relevant struct information.  The patch is attached.

I generate the xparameters_ml403.h file using Xilinx's EDK base system 
builder wizard.  However, the wizard does not automatically enable the 
Cypress device to be interrupt driven.  I have manually done this as 
described in the attached patch.

The resulting xparameters_ml403.h has the following defines:

sellsa@SS-SBIR-Ubuntu:~/spacesuit/linux-2.6-xlnx$ cat 
arch/ppc/platforms/4xx/xparameters/xparameters_ml403.h | grep USB
/* Definitions for peripheral CYPRESS_USB */
#define XPAR_CYPRESS_USB_PRH0_BASEADDR 0x80800000
#define XPAR_CYPRESS_USB_PRH0_HIGHADDR 0x8080FFFF
#define XPAR_SYSTEM_USB_INT_PIN_MASK 0X000001
#define XPAR_XPS_INTC_0_SYSTEM_USB_INT_PIN_INTR 0

When I boot the Xilinx ML403 board up, I get the following:

Sam, since you have this working, any help would be greatly appreciated. 
  What else do I need to do in order to get USB host working on this board?
