Make sure your Java implementation rxtxcomm isn't too stupid to look for
USB ports. There were endless problems with some old versions of rxtx with
JMRI and USB serial ports.
Also as the same user try stty -a </dev/ttyUSB0. That will if it's
behaving sensibly dump the terminal state (speed etc) on your screen.
If that works you've almost certainly got a problem with your java.
