This function initializes the USB process.

This function enables the USB controller and init the USB interrupts. The aim is to allow the USB connection detection in order to send the appropriate USB event to the operating mode manager. Depending on the mode supported (HOST/DEVICE/DUAL_ROLE) the function calls the corresponding USB mode initialization function
