Step of add usb(sl811hs)?

Dear:

i am glad to see so much boys had been used SL811HS in NiosII. i have done something about it:

1.write a schedule module in verilog HDL in order to convert avlaon signal to sl811 signal.

2.add the module to NIOSII as an user defined logic. and set the pins to J16(cyclone board).

I don't know what can i do next step!! such as how to set uclinux kernel(2.6.9), how to add usb driver code....... Can you tell me the detail step????

Thank you very much!!!
