1. Open Device Manager and uninstall the current adapter in SD Host Adapter flag.
2. Restart the PC. Updated adapter will installed (Mobile 6th/7th Generation Intel Processor Family I/O SCC: SDCard - 9D2D). The SD card will work.
Still there are another problems not related to Windows. See the discussion in the following link:

Thanks for this fast answer.
I have changed the driver, like you proposed and the SD host adapter seems to work fine, only after a "computersleep" the adapter comes not alive, he stays in sleep.
You welcome. As you can see in the above mentioned discussion, Intel have experience the same issue in their lab and I believe they will found a solution. In my opinion, there is a problem in handshake between the driver and the Operating System.
Now i changed my configuration: sleep conditions:
display: 20 min
With this condition the card reader seems to work always, but the cpu activity is now all the time : 42%.
We are working on this, form this point I recommend you to install all windows updates
After that please let’s try installing these drivers:
Intel® Management Engine Consumer Driver for Intel® NUC:
Intel® Chipset Device Software for Intel® NUC:
Intel® Serial IO Driver for Intel® NUC6i[x]SY:
Please let me know if it helps you.
I've tested the system with the all updated drivers already before I address the problem to Intel and didn't help. Today I've reinstalled the drivers per your instruction and again with he same result: high CPU consumption, even after the SD card is removed.
Thank you already for the investigation you have done.
First this is my configuration:
- NUC6i5SYH 6260U 1.8Ghz 1.8Ghz
- 16 Gb RAM DDR4
- UEFI BIOS 0045 2016
- Samsung 950PRO 256 Gb M.2
- Crucial BX100 SSD 250 Gb
- Win 10 Pro 1607 14393.51 64-bit digital licence
With this configuration I have a problem with the SD-card reader. Recognition and a high CPU use (44% ntoskml.exe).
This finishes only after a restart.
There is no good result after the reinstallation of the drivers you mentioned.
There is no problem with the card if this is used in a extern USB device.
I have also a problem with some strange sounds, especially when the CPU goes in sleep or is in sleep.
The sound is the same you hear by using or stopping a USB device.
Second i have an other PC:
- Pentium Dual Core CPU E5300 2.6 2.6
- 4 Gb RAM
- 500 Gb HD SATA
- intern SD Card reader
- Win 10 Pro 1607 14393 32-bit X-64 digital licence
With this configuration: NO PROBLEM
I hope that you can resolve the problems with this information.
I format a SD-card NTFS to a SD-card FAT32.
Now the card works every time by inserting in the cardholder, but the CPU stays always on 44%.
With NTFS you can use the card only 1x. You need a restart for futher use.
Is the system of the card-holder 32-bit ?? in a 64-bit architecture ???
My SD-Card is a SAMSUNG Electronics Co., Ltd. I don't know model or type. How can I see this ???
I have upgrade my CPU with KB 3176936 and KB 3176934 (24/08/2016)
Is there a relation between this upgrade and the issue ??
Greetings and thanks.
This problem is not related to SD card model, neither to Windows update. As I've explained in the following thread, it is happening (the CPU power high percentage consumption), also if an empty SD card adapter is inserted to the slot. To stop this phenomena, NUC must be restarted.
Please read this thread:
As I understand, Intel has Mr rguevara has duplicated this problem in Intel lab. So, now you need only debug it (because from my experience, once you can duplicate problem, you have already "half solution".
