Just be aware that the USB-serial converter can be polled only every ms.
So if you have really time critical applications you may see some
porblems. I've spend days no knowing why I wasn't able to program a avr
microcontroller till trying a real serial device (without USB) and it
suddenly worked.. So if someting does'nt work maybe try a real serial
interface first :)
