I made a lot of changes to the KoboTouch driver in the latest version of calibre. Most of them were in the configuration. The error you are seeing is in the code to migrate the configuration. Can you try opening the driver configuration? If you can, make a change to something in it and save the change. This should fix the configuration and the device should connect properly.
If this doesn't work, you will need to delete the existing configuration. This is in the file "device_drivers_KOBOTOUCH.py" in the calibre configuration directory. Delete this when calibre is not running. Then configure the driver before connecting the device.
