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. -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
