I just built a Nanode and it worked with the usual sample code on Ubuntu 10.10 but not on 11.10, which pukes out the below complaint. It blinks (LED on pin 6, opposite polarity) when I try to upload, then quits and disconnects the serial port (grayed out) until I re-plug it in again, then it finds the next USB port. Then the same happens again. That is, uploading seems to shut off the port and the next time I plug it in, it goes to the next USB port and tries again, uselessly. The serial loopback doesn't work any more either. Binary sketch size: 998 bytes (of a 30720 byte maximum)processing.app.SerialException: Error opening serial port '/dev/ttyUSB3'.
