XD vuelvo yo .. jejeje...
bueno el problema es el siguiente ando programando un sw para un usb hid con un micro 18f4550, el compilador pic c no registra ningun error pero cuando lo quemo el dispositivo usb no lo reconoce el pc, ni siquiera dice que ay un dispositivo en el puerto.....
si alguna persona puede colaborar se lo agradecería mucho...
