SD Card Slot Disappears After Sleep (Gone Until Reboot)

Nope, I don't wish to do that. This is an astonishing 3+ year old driver bug which users in this thread have found against multiple operating systems. I expect working drivers, from Apple. Can someone post legitimate links to where apple are dealing with this problem, I don't any real information about this issue being dealt with: where are the filed bugs, the responses?

Each bug filed by an individual is not publicly visible. The reporter should provide updates.

As the Windows patches/KBs show, it is not a driver issue, but a Kernel issue. From https://support.microsoft.com/en-us/kb/2990172 ,

Do you still think this is a Driver Issue?

That KB is about SD cards not being recognized on win 8, the problem we are having is that the card reader disappears entirely on any version of windows, and various other operating systems on all models of retina macbook with a specific chipset.

On a 2012 non-retina MBP, with a Broadcom SCSI driver on W8.1, it does not. On a 2013 rMBP (W7 Professional), it works fine. This is from a 2013 rMBP.

Linux device probes (Ubuntu and Fedora) seem to work fine. The KB has this.

When you insert an SD card into the SD card reader, the SD card cannot be recognized in one of the following scenarios:

• Immediately after you wake the computer from sleep mode.
• The computer does not go to sleep but the SD card reader is idle for a long time without an SD card inserted.

This points to the kernel not probing the devices correctly. The two models I have do not show any issues with OSX, so the same chipset/firmware seems to work fine.

Are there any events about PnP in Windows Event Viewer which are USB-related?

The bugs that have been filed should also be looked at to check for any progress.

You didn't specify under what conditions you took your screenshots: let's be clear: the problem we are having is that the card reader disappears entirely on any version of windows AFTER RESUMING FROM SLEEP, and various other operating systems on all models of retina macbook (you seem to have ascertained in previous posts that this relates to a specific Broadcom chipset? I have that chipset, but I think its a very common chipset for retina macbooks, right?)

There are 7 pages of posters here over many years and many operating systems indicating this isn't true. Looks like when many people with Retina macbooks and Broadcom chipsets shut their lids, the SD card reader disappears.

Nothing I can see which helps the issue.

But you said only the person posting it can see the bug. Private individuals can't be responsible for communicating over this issue, surely?

This is why I highlighted the 'Immediately after you wake the computer from sleep mode.' part. The 2012 MBP has a different driver. But the Broadcom chipset for the Card reader is very common on Macs and other non-Mac PCs. If OSX can handle it properly on the same chipset, the higher layers are not working correctly. I have seen Resume-from-sleep create additional instances of the same card, an in one specific case, due to VID/PID/SUBSYS differences in the device tree. Fedora and Ubuntu work fine. Windows is the only one I have seen this issue with.

This is specific to Windows. The drivers do support Windows. Sleep/Wake/Hibernate and the state of the machine has interaction with the drivers. After a Wake, the OS kernel (of any OS) is expected to probe the PCIe bus(es) for any new state information and rebuild such state if necessary. The VID/PID/SUBSYS issue is very specific and is known to cause problems. Windows compounds these problems even further, by incorrectly probing device state. For example, if you swap the SD card (say you insert a 64GB SD card and the card inserted when the computer went to sleep was 32GB only), the OS should get device information properly. This is why each device is assigned a UUID, and the PCIe/Driver layer is supposed to notify the OS that it has changed. Some OSEes do not do this properly. You can always say it is a driver issue. I would expect PnP events indicating such change. You can try this as an experiment and see how it works on Windows and OSX.

What I am suggesting is that the posters on these 7 pages who filed bugs can/should report status of the bugs that they filed. It would help all others with progress on this issue.

I've got the same problem. The internal card reader doesn't open when I insert an SD card. I checked the "About this Mac" and got this message, This computer doesn't contain any Apple Internal Memory Card Readers. And I couldn't get it to read from a USB card reader. Have you resolved this issue since you posted it ? I'll get it back when I do a Reset the System Management Controller (SMC0:I shut the machine down, unplug it for 15 seconds and then plug it back in, and restart. I then have my internal card reader again, until the Mac goes to sleep or I put it to sleep. Then when I awaken the machine, the card reader is gone again.

Can you disable Sleep/Hibernate and test?

The card reader remains active until the Mac is put to sleep manually or automatically. It disappears only after the Mac awakes from sleep. The two events are some how connected.

Before sleep/hibernate Windows should preserve the device state. After Wake, it should re-probe all devices, notify the user of any changes in the devices or their state to the user. For example, you can replace the SD card before the computer is Awake, and notify the user of any changes. Events reported to the Windows kernel get lost/ignored causing problems.

Rather than ask users to mediate between MS and Apple, someone from Apple should pick up the phone. MS have wholeheartedly adopted a continual update model now, I'm sure this could be fixed with some communication. These posts aren't going to stop coming in, that should be very clear at this point!

Bootcamp users are a 'fringe' group (at least for now). Both the behemoths tend to ignore the other (except when Jobs had Gates invest in Apple). 😉

I feel a bit better when I saw this thread knowing that I am not the only one who has this problem. But instead of SD card disappearing time to time , I also suffer from other problems caused by it I believe. when the card reader is not recognized , and i press the 'option' button to switch between Win and Mac , it takes 90~120 seconds to show the boot selection screen. And the touch pad and key board lagged a lot ! I only saw people here complaining the SD card recognition problem. does it mean that none you you guys ever experienced the issues i have ?

I'am using 2015 MBP ,128G, 4G,retina .

No sorry I don't see that behaviour at all.

BUT: since a raft of windows updates I installed today, behaviour has changed. Instead of silently failing, when I resume from sleep I often get this:

1) under Universal Seraial Bus Contollers in Device Manager, we have an atserisked 'Unknown USB Device (Port Rest Failed)' - that sounds like progress, right. Something has tried to reset the port at least, rather than silently failing.

2)A popup says "USB device Not recognised - The last USB device you connected to this computer malfuntioned and Windows does not recognise it. Recommendation: Try reconnecting the device. If Windows still does not recognise it, your device may not be working properly."

I agree, my device (sd card slot driver) is likely not working properly.....

Also now it seem the card slot disappearing can now persist over reboots, only a shutdown or reboot to osx will make it come back.

I get exactly the same behavior, except even a reboot to OSX doesn't bring it back.

Hello,

I have the same problem with El Capitan, MacBook Pro (Retina, 13-inch, Late 2013).

The SD Card is visible after reboot, vanishes after returning from Sleep.

Even if I pop it out and reinsert, the SD is not visible, nor mounted.

Any suggestions?
