Средства и методы разработки

CE5 проще, работает быстрее, что бы тут не говорили, ресурсов меньше жрет... В твоем нафигаторе на SirfIII (CE5) переводится в режим хоста заменой одной цифирьки в реестре или вот этой утилиткой. USBSER_class - это то же самое, разница в значении ключика "DeviceArrayIndex" , который указывает одному и тому же драйверу работать как простой CDC, а не в режиме ActiveSinc.
