I need some help to understanding the PIC18f4550 - ( USB interface exactly)

I'm working on my graduation project and i will use the pic18f4550 :

1- Connect MMC
2- USB - device

There's plenty of examples on MicroChip.com, and you might look at the USB Bitwhacker project (which references many of the same files).
