Randy Syring, we can see what can be done anyways without it. However, please keep expectations reasonable as not testing the upstream kernel limits the probability of getting this addressed as fast as possible.
With this in mind: 1) Do you have the 2013 or 2014 model as per https://support.apple.com/en-us/HT201518 ? 2) To see if this is resolved in Ubuntu, could you please test the latest live Ubuntu via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? 3) Do you have a dual-boot of macOS and Ubuntu? If so, is the latest version of macOS installed? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1531653 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 [ 2.681478] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 2.681498] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 1 [ 2.681589] xhci_hcd 0000:00:14.0: cache line size of 256 is not supported [ 2.681607] xhci_hcd 0000:00:14.0: irq 63 for MSI/MSI-X [ 2.681755] usb usb1: Manufacturer: Linux 3.13.0-57-generic xhci_hcd [ 2.682098] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 2.682115] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 2 [ 2.682219] usb usb2: Manufacturer: Linux 3.13.0-57-generic xhci_hcd [ 3.980423] usb 2-1: new SuperSpeed USB device number 2 using xhci_hcd [ 9.352422] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 14.560476] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 20.549170] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 25.757227] xhci_hcd 0000:00:14.0: Timeout while waiting for address device command [ 26.129482] usb 1-1: new high-speed USB device number 2 using xhci_hcd [ 26.321707] usb 1-3: new full-speed USB device number 3 using xhci_hcd [ 26.505802] usb 1-5: new full-speed USB device number 4 using xhci_hcd [ 26.603224] usb 2-1.1: new SuperSpeed USB device number 6 using xhci_hcd [ 26.754245] usb 1-1.2: new low-speed USB device number 5 using xhci_hcd [ 26.954315] usb 1-1.4: new low-speed USB device number 6 using xhci_hcd [ 27.050323] usb 1-3.1: new full-speed USB device number 7 using xhci_hcd [ 27.142383] usb 1-3.2: new full-speed USB device number 8 using xhci_hcd [ 27.234476] usb 1-3.3: new full-speed USB device number 9 using 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.
