Muchas gracias J1M. Hice lo que me dijiste y todo se solucionó.
Aclaro que el cambio que hice fue cambiar la línea:
#include "C:\Program Files\PICC\Projects\usb_BOOTLOADER.h"
y no cambié la línea
#include "C:\Program Files\PICC\Projects\usb_cdc.h"
pues me quedo sin usb
Ya tengo por fin mi dispositivo usb cdc.
Se que con las lineas que me dio J1M reservo el espacio del bootloader para que la aplicación
no interfiera con su espacio de memoria, además que ubica el vector de reset y de interrupciones
pero finalmente no se que parte del archivo usb_BOOTLOADER.h tenía el problema.
Lo muestro a continuación y si saben el problema y por qué, agradecería mucho.
