[Roland <1006765@xxxxxxxxxxxxxxxxxx>]

Tried the latest  3.12.0-031200rc4-generic  64bit Kernel
This works much better:
- booting with card and USB-disk (USB-powered) inserted, is always working
- plugging in card first and after that a device, is not working
- plugging card with USB stick, work, but takes a long time
- plugging card with USB-disk (USB powered) together dousn work, and gives slow mouse response
- plugging card with USB-2-hub attached always works, it's possible to plug in/out disks and usb-sticks, but is slow
sorry I don't have a USB-3 hub, will buy one, if this works it's a very good work-around !!!
regards

Title:
  1033:0194 Hot plugging USB3.0 express card Not possible

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On my Lenovo T520 hot plugging USB3.0 PCI Express card not possible.
  Hot plugging USB devices in this Card is also not possible.

  Only way to access the card and USB device: is powering on with PCI
  card AND USB devices connected. Reconnecting devices after this is not
  possible. Re-Plugging the drive but also other USB products, are not
  recognized.

  WORKAROUND: sudo echo acpiphp >> /etc/modules
  Modify /etc/default/grub to have:
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pciehp_force=1 pciehp_poll_mode=1"

  and run:
  sudo update-grub
