--- Comment #1 from Hans Petter Selasky <hselasky at FreeBSD.org> ---
Hi,

Some ideas:

Have a look at the USB traffic using usbdump tool. It will show what is going
on at the lowest level.

Are you using libftdi?

Are there any other applications which use libusb to communicate with the FTDI
chip instead of /dev/cuaUX ?

--HPS
