SD card can't be hot-pluged on Win10 with Bay Trail CPU(E3800) RRS feed

  • Question

  • Hi sir,

    I try to hot-plug the SD card on Win10 with Bay Trail CPU(E3800) and the system can't detect the SD card.
    If the SD card inserted on device and restart the computer, it can be detected, but hot-pluged will fail.
    If the SD card doesn't insert on device and restart, the SD card can't be detected when I insert the SD to device.
    I also try to enable/disable the SD Host Controller or rescan device on device manager. This step can help to detected SD card.

    My SD card brands are Innodisk, Kingston and SanDisk. All of the sd can't using hot-plug function.

    All of the Windows Update have been installed.

    There are 5 case I had tested:

    1. E3800 with Win7 Embedded -> OK, hot-plug is working properly.
    2. E3800 with Win7 Pro -> OK, hot-plug is working properly.
    3. E3800 with Win8.1 Pro -> OK, hot-plug is working properly.
    4. E3800 with Win10 LTSB 2016 -> Fail
    5. E3800 with Win10 Pro -> Fail

    In addition, I try to copy the Win8.1 Pro SD card driver to replace Win10 SD card driver. After replace the drivers, SD card can hot-plug on Win10.
    Here are the drivers I replaced:
    - dumpsd.sys (6.3.9600.16384) replace dumpsd.sys (10.0.14393.1358)
    - sdbus.sys (6.3.9600.16384)  replace sdbus.sys (10.0.14393.1358)

    Did you have any hot-fix file to fix this issues?
