Añado informacion;
He estado estudiando el tema VID y PID,
dentro del archivo "inf" tengo la siguiente informacion :
Hasta ahi todo correcto.
Supuestamente el archivo usb_desc_cdc.h contiene la informacion del VID y el PID,
por mas que lo cambio, lo trasteo, lo compilo y lo cargo al pic 18f4550 del proteus, cuando inicio la simlacion me detecta un dispositivo con el nombre "serial demo", que era el que trae por defecto la libreria de proteus, y no consigo instalar el driver de ninguna manera.
Sabeis por donde pueden ir los tiros??

; Vendor and Product ID Definitions

; When developing your USB device, the VID and PID used in the PC side
; application program and the firmware on the microcontroller must match.
; Modify the below line to use your VID and PID. Use the format as shown below.
; Note: One INF file can be used for multiple devices with different VID and PIDs.
; For each supported device, append ",USB\VID_xxxx&PID_yyyy" to the end of the line.
