I have not found a reference to this feature in the current FTDI lib,
sorry if a patch has already been posted.
Here is a quick patch to the current libftdi GIT HEAD to support
hi-speed baudrates on recent FTDI devices

I've kept the original 5% tolerance on UART speed, although many
devices do not tolerate such a drift at hi baudrates (I'm using a 3%
max tolerance with my own devices)


libftdi - see for details.
