If I'm not mistaken pl2303 based cables have/had problems handling baudrates above 115200, there was a recent update into the kernel tree, but I've never tested it.
the problem is not "[standard] baud rates above 115200" but it is "non-standard baud-rates at all". Normal USARTs have baud-rate generators that can only generate baud-rates "input_clock / divider" where divider is either an integer, or even more: limited to a power of 2
The calypso cannot do any standard baud-rates above 115200. That's why you need a USART with more flexible baud rate generator. The most commonly known one to do this is the FTDI series of USB-serial converters.
