Did the firmware update to 4.0.2.0 for the uPD720200a card
(had to find a Windows note-book, while I'm running Ubuntu 12.04/64 on a Lenovo T520)

Problem is the same, Also see exactly the same behavior with a Dell/Windows7/64

disks and usb-sticks are only accessible, when booting the pc with USB30 card AND HD or stick plugged in.

if removing the disk/card or the USB30 card , the card isn't accessible.

strange thing, with lspci, the card is visible, although it's plugged out (and NO lines in the kernel logging)

lspci with card plugged in:
05:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04)
lspci with card plugged out:
05:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev ff)

you see, revision is not readable
