What do you mean by USB UART and USB FIFO?
IS USB UART a USB to RS232 ?
So What's USB FIFO?

Re: USB UART vs USB FIFO

USB is very "bursty." For several milliseconds, no data will be transferred, then suddenly a chunk of your data will transfer at high speed, and then you'll have to wait again for the next high speed transfer. To help with that problem, the FTDI FT232BM chip has an internal FIFO buffer memory. If your project required bit-banging COM port pins, you may have to redesign your algorithms to accomodate the bursty USB FIFO architecture.
