From https://www.samsung.com/semiconductor/minisite/ssd/product/portable/t5/ I learn this is a USB 3.1 Gen2 device, not a Thunderbolt device, so authorization isn't relevant (and thunderbolt-tools isn't the relevant package).
Still, the fact that you had to force power the controller even when a device is connected (and especially as it works when it's connected on boot) suggests there is some sort of issue between the BIOS / port controller / cable / maybe other parts in the system that take part in the HW detection. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830930 Title: USB 3 devices are not detected on thunderbolt 3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbolt-tools/+bug/1830930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
