FTDI is in the process of announcing their second generation of '232 and '245 chips which will begin sampling early in Q3, 2002 and cost about the same than the first generation. Their additional features include,
-- Reduces external component count with Integrated Power On Reset and RCCLK circuitry
-- Improved power management control for USB bus powered and high current devices
-- Includes a USB Isocronous data transfer mode
-- Integrated level converter on UART for 5V and 3.3V logic
-- USB 1.1 and USB 2.0 compatible (Full Speed only)
А так, макет на модуле USBMOD2 http://www.gigatechnology.com/usbmodprod.html у меня заработал с пол-пинка. Грабли есть, но связаны не с чипом, а с Виндой и самим USB.
