$ export MOTECOM=serial@/dev/ttyUSB0:tmote
$ java net.tinyos.tools.Listen
Error on serial@/dev/ttyUSB0:57600: java.io.IOException: Couldn't
configure /dev/ttyUSB0

$ export MOTECOM=serial@/dev/ttyUSB1:tmote
$ java net.tinyos.tools.Listen
Error on serial@/dev/ttyUSB1:57600: java.io.IOException: Invalid port.
Known serial ports:
- /dev/ttyS0
- /dev/ttyS1
- /dev/ttyUSB0

So the ttyUSB0 is the correct port. But, for some reason, java cannot
configure it.
You know of any other kind of tests I can do to the serial port to
diagnose the problem?

Thanks,
Fabrizio
