Public bug reported:
I found a strange problem when trying to connect my Samsung T5 SSD.
If I connect it to the Thunderbolt port on my HP EliteDesk Mini G4, with
Thunderbolt at boot then the SSD is detected without issues.
If I unplug it and reconnect then it's not detected.
If I force the thunderbolt controller on (boltctl power -t 1) then I
can see the new USB host created in lsusb but the attached device is not
added. No additional events are shown in dmesg.
If I connect the device using another cable then it also doesn't work
I have a USB-C cable only rated to USB 2.0 speed then the device is
recognized without any issues.
