Go look here:
http://ww1.microchip.com/downloads/en/AppNotes/00956b.pdf

Then download the trial version of the C18 compiler. Study the source code and then port it to CCS

I asked CCS:

"I have been using the CCS compiler for development of our product. Microchip has release their PIC18F2550 which we want to use to add "USB 2.0" interface. Is CCS supporting this and if so what is the time frame
for the release of the compiler that will support these chips?"

Their response:

"Our USB library supports this part but at this time we only have the
USB 1.x functions defined. It will probably be 6-10 weeks before the
2.0 functions are ready"
