Standard SD Host Controller Miniport
This is a sample for a Secure Digital (SD) Host Controller miniport driver. The driver works in conjunction with sdport.sys, which implements SD/SDIO/eMMC protocol and WDM interfaces, to provide the host register interface.
This sample builds a Windows Universal driver. It uses only APIs and DDIs that are included in Windows Core.
This driver, sdhc.sys, provides a functional miniport implementation for a standard SD host controller.
However, it does not have support for many more recent features such as:
UHS-I speed modes.
