Technically it is a USB drive for the host, but it is not possible to pass through the device as a USB drive.

After an upgrade from vCenter 5.5 to 6.0U1 everything looks fine but the vCenter DB was still running in a SQL Express instance. Because this is an unsupported configuration it has to be fixed.
