Check /dev for other ttyUSB# entries. It happens with other devices as well. I periodically use a USB connected Arduino. If I plug it back in too quickly it will go to a new com port. If you unplug your device, simply wait a few seconds (well, sometimes a minute) before plugging it back in. The software gurus here might be able to tell us where we can set the time out to make it a bit quicker for the unplugged device to go away, or some neat trick to make the device reuse the existing entries.
