Q: SD Card Slot Disappears After Sleep (Gone Until Reboot)

I love my new Macbook Air 2013. Its speedy Core i7 and lightening-fast 256GB SSD make for quite a wonderful experience in Windows 7, too. But I have a problem that is proving to be quite the frustrating little niggle, and I just can't sort it out. So I've turned to you guys for help.

 

Here's the thing: the SD Card (the slot, the device, the card, the folder, the drive, everything) just vanishes after the MBA wakes up from sleep. I've tried it with various cards with different filesystems (FAT32, NTFS, EXFAT) and capacities (32GB, 64GB, 128GB) -- always the same. I've reinstalled Windows 7 Pro x64 multiple times using up-to-date boot camp assistant and Apple Support Drivers.

 

The card works fine. Until, of course, the computer goes to sleep. When it awakens, the card is gone -- even from the device manager -- until the computer is rebooted. That's right, plugging the card (or any other card) into and out of the slot doens't fix it. Neither does resetting the NVRAM or SMC. Neither does adding an event to the Task Scheduler to disable the device prior to sleep and re-enable it on wake (it doesn't re-enable, the entire device vanishes).

 

Here are some more details:

- Putting the card in for the first time while the computer is asleep is okay -- the card appears when the computer is awakened. But putting it back to sleep afterwards causes the same behavior -- the card and reader disappear until reboot.

- The computer can go to sleep and wake up many times without a card inserted without the device disappearing. I can put a card in and have it recognized propertly after any number of card-free sleep-wake cycles. But the moment the computer sleeps with card inside, the reader disappears until next reboot, no matter what.

- This behavior does not occur in OSX to my knowledge (although OSX handles both mounting AND sleep states VERY differently than Windows, so I can't directly compare).

 

I have tried everything short of scripting a reset of the root USB hub (a highly unrecommended procedure that can disable the keyboard/mouse/etc). I've even tried new USB hub drivers (intel 8.10) to no avail.

 

Anyone have the same issue? Does this work for you? Does anyone have a copy of older SD card drivers (maybe the latest ones are screwy?). Thanks

MacBook Air (13-inch Mid 2013), Windows 7, OSX 10.8.5 too.

    There is no other driver installed for that device.

    The greyed out "Apple SD Card Reader" device disappears after resume/hibernation with Code 45:

    Posters have different hardware, including MBPs, with different SD Controllers. You can see I have a Broadcom controller.

     

    Can you post the following screen from the OS X side, with the SD Card plugged in?

    We have different vendor ID's too.

    You may need to find another model with an Apple SD Card reader and check if the BC Drivers version for that model is different and verify if it will work on your model.

    hm okay. Thank you for your support Loner T. After contacting some other people with the same hardware and same problems within a clean windows 8.1 installation I still believe it is a driver related issue and will contact apple support. Or maybe someone else of Apple will read this thread... :-)

    Do you have an external USB Card Reader? You can try that, assuming your USB devices do work properly across sleep/wake and hibernate/wake.

    Thanks for that hint. I already tried an external USB card reader without any problems after standy-by...

    On a late 2013 15" rMBP, with the same driver version that you have, the SD Card works properly on a W8.1 64-bit (but it is an EFI installation of Windows, not the traditional BC/Windows MBR installation).

    What about the reader driver version from Apple (within the USB section of device manager)? Your screenshot shows the driver for the disk device section...

    The Card Reader stops with Windows Error Code 43 at times (Unknown USB Device (Link in Compliance Mode)). I can disable the device, re-enable it and it works properly after that. I will post some screen shots next time it happens. You may want to check under Device Manager -> Universal Serial Bus Controllers section and check if you have an entry with a yellow triangle and exclamation mark when this happens.

    Ok, but that looks like a driver bug too: The card reader should not stop working... It might be ok for you to restart the device. But for me it is not an appropriate behaviour of a storage/disk device which i want to be reliable.

     

    In addition your workaround doesn't help me: The device disappears in my device manager/error code 45. So I am not able to re-enable it in the way you suggested.


    Since we not heading towards a solution I think we should stop here. Thank you for your help!

    Same issue with Macbook Air (Mid 2014).

    I tried to disable USB Selective Suspend in power settings, but it doesn't work.

    I believe it's a driver related problem.

    I placed a bug report in Apple Bug Reporter and will let you know, if there is any serious outcome/reply/solution from Apple.

    Very rarely does Apple update the BC Driver bundles. If OSX works as expected, there is very little incentive for Apple to fix it.
