I have a Seagate Expansion Desktop Drive which is an external 2 TB USB 3.0 disk that I use for testing. The drive is attached to a USB 3.0 port on my Macbook Pro in one test, and to a USB 3.0 port on my Mac Mini for another test. Both the Macbook Pro and Mac Mini have virtualbox installed and have a Ubuntu guest installed. The drive should be accessible to the ubuntu guest.
My current setup:

Is it a Virtualbox issue or a Ubuntu issue? Could VirtualBox not be returning a correct USB controller, or?
Incidently the Drive works on a dedicated kubuntu workstation, and in a Windows 10 VM from the same macbook pro.
