#1
What version of the Linux kernel are you using, or are you running Mac OS X?
Have you tried running selfUpgrader.py again? If not try that. If that fails unplug your U3, wait 5 seconds, reconnect and try running selfUpgrader.py again. Also, the LJSelfUpgrade section of the U3 User's Guide provides helpful troubleshooting information if programming fails: http://labjack.com/support/u3/users-guide/1.2
Also, another alternative to hacking the code is to download the U3A firmware file, and to specify to use this file with the -f flag (example: python selfUpgrader.py -f path_to_file/U3Afirmware_144_12112007.hex 3).
Let us know if nothing works. Worst case is that the firmware could of been corrupted beforehand, or during the upgrade. I mention beforehand since your U3's firmware version looks suspicious as version 0.100 is not valid. In this case email support@labjack.com and we can talk about an RMA.
