Which arduino board and arduino software version? Uno requires at least arduino software version 0021.

You are correct.  /dev/ttyUSB?

If the duemilanove has power
First thing I would do is try a different usb cable.
Then I would try running the arduino software as root (sudo arduino).
If running as root works:
    run the command "id" to ensure to you are a member of the dialout group. Add your user id to /etc/group if required
If running as root did not work (with the duemilanove plugged into the usb port):
    execute the command "dmesg".  look for a entry that looks like, "FTDI USB Serial Device converter now
        attached to ttyUSB0"
    execute the command "lsusb",  look for the entry, "Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC"

Post the output of these command.
