Title:
  Unable to hotplug ExpressCard in 12.04.4

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  There is a similar bug 1091125, but this one is slightly different

  Steps:
  1.  Install 12.04.4 + update (3.11.0-18)
  2.  Hotplug the APIOTEK usb 3.0 adapter ExpressCard
  2.1  Hotplug a USB stick on the ExpressCard
  3. Hotplug the APIOTEK usb 3.0 adapter ExpressCard with a USB on it

  Expected Result:
  * The ExpressCard should be hot-pluggable

  Actual Result:
  The following message will shows up in dmesg:
  * plug the ExpressCard
  [  748.270195] pciehp 0000:00:15.3:pcie04: Card present on Slot(0-1)
  * Connect a USB stick to the ExpressCard
  (Nothing happened)
  * unplug the ExpressCard
  [  756.122707] pciehp 0000:00:15.3:pcie04: Card not present on Slot(0-1)
  * plug the ExpressCard with USB on it
  [ 1199.593797] pciehp 0000:00:15.3:pcie04: Card present on Slot(0-1)

  Cold plug works fine, and when it's cold-plugged, usb hotplug works as
  usual.

  Debugging information:
  acpiphp module cannot be found in lsmod
  I can't load that module manually with this error message: 
  FATAL: Module acpiphp not found.
