I updated BIOS by saving exe file to usb stick and used bios update option from BIOS boot menu. For TB18DC firmware upgrade, I installed Windows 10. Actually firmware upgrade did not go too smoothly (it upgraded successfully some subsystems, but not all, failed with MTS1, MTS2).
Here are some bios settings that might be related: Thunderbolt Adapter configuration: - Thunderbolt: Yes - Enable thunderbolt ... modules: no - Enable thunderbolt boot support: no - No security: yes - Always allow dell docks: yes - Enable USB Boot support: Yes - Enable external usb port: yes - Enable usb powershare: no - Thunderbolt Auto switch: no - Bios Assist enumeration: yes -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766076 Title: USB over thunderbolt turns off every once in a while To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1766076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
