Пытаюсь на LPC2148 скрестить AudioUSB с виртульным сом портом, получаю  
такой длинючий дескриптор, VIRTUAL_PORT_ENABLE включает часть дескриптора отвечающую за роботу вирт. порта, соответственно AUDIO_USB_EANABLE включает аудио юсб.
Та вот по отдельности когда включен либо аудио юсб либо порт все работает нормально, а вместе не хочет в чем может быть проблемма?
