Hmm, it seems you need to read the ABCs of USB before embarking
on this project.

As for your issue, you may want to check if your hardware and
firmware are correct or not. If possible, get a known-good hardware
(eg: the dev kits from Microchip) and then use the known-good
Microchip USB firmware framework to get familiar with the
stack first.
