Well, that's progress in a way.  If you haven't done it already I'd try every
USB port available.  Might be a wiring error on the board.
Another thought is that the Generic driver might not be supporting all the
functionality of the USB3 controller as well as a driver which targets a
specific controller type, such as the Intel USB3 controller on the SuperMicro
Note that the Generic driver reports that the controller on the HC is limited
to 32-bit DMA transfers.  Can't say whether that's correct since I know nothing
about the controller being used.
