I do the same thing with my FT232RL's.  The issue is, when you grab
the USB device with the FTDI library (or the D2xx library), you grab
the whole device - including the serial port.  At that point, you need
to use the libftdi API to see the serial port, not Linux's built-in
tty driver.

Basically, you can't have two drivers talking to the same usb device
at the same time.
