Symptom

I'm trying to update the Connect ZBT-1 firmware using Ubuntu and Chromium. I get a message that the connection failed.

Resolution

1. Make sure hot plug support is enabled, as described in this Ubuntu forum post
2. Make sure your user is added to the dialout group: sudo adduser [username] dialout
3. Reboot your system.
4. Try again.
