i can use elektorSDR plataform

in windows XP with elektorSDR software.
I'm cursing a few weeks ago, because I want to install in linux OS.
i.e. i try to use elektor SDR plataform in ubuntu 9.04 and i can't.
i download ftdi shared librery (libftd2xx.0.4.16)
after, install a gnu radio canpain (GRC)
i put a "lsusb" in a terminal and appears the manufacturer's name
(Future technology Devices International, Ltd FT232 USB-Serial (UART) IC), but
i run fitdi samples, and not recognized the plataform
please, help
how put on operate?'
