Title:
  Macbook Pro Retina 11,1 SD Card Reader Doesn't Work

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Macbook Pro (MBP) Retina 11,1 with an SD card reader that
  will not work.

  The SD card reader:

  * has device code 05ac:8406
  * does work in OS X.
  * does not work in SystemRescueCD running kernel 3.14.56-std461-amd64
      - I have a friend with an identical Macbook Pro and his SD card reader does work in SystemRescueCD
  * Does not show up in lsusb
  * Does not display any messages in dmesg when an SD card is inserted
  * Device 05ac:8406 does not show up in dmesg
  * Does not work in kernel 4.2.0-22.27~14.04.1.  All issues reported here seem to be the same regardless if I use 3.13 or 4.2.
  * Uses the following drivers on my friends MBP: sd, usb-storage, usb, xhci_hcd

  The last point made me look closer at the xhci_hcd logs:

  rsyring@loftex:~$ dmesg | grep xhci_hcd

  [   81.685139] usb 1-1.4: new low-speed USB device number 10 using xhci_hcd

  The "Timeout while waiting" messages are suspicious to me.  dmesg on
  my friend's MBP  does not show those messages.
