C67x00 driver and usb keyboard

Hi all,

Good News:  I got the C67x00 driver to work with my ppc-405 + cypress usb controller!

I had to get the calls right to the cypress chip about turning on the power to the ports. Our HW people wired all 
that stuff up for us.  So I had to make some pins outputs and turn them on.

Usb storage works.  I can get udev to create a device and I can connect and use it.

BUT I cannot get a keyboard or mouse to work.

I have:
1. turned on all the keyboard stuff in the kernel
   keyboard.o is being made, all the usbhid stuff is being compiled (made it a module).
2. loading the modules detects a usb keyboard and fills out the right id and vendor.
3. loading a mouse fills out the right id and vendor.
4. I have set my xwindows kdrive.cf to use XKB.

I don't know, anyone have any debugging tips for usb keyboards?
My big problem is I cant find any good info on how usb keyboards are supposed to connect to the kernel and X.

I have a custom kernel, plus the c67x00 driver.
HW is a Virtex4 with builtin PPC-405 and cypress c67300 usb controller.
Xfree 4.3.0 building the kdrive, small X windows.
