If you are facing this problem on a Windows device, follow these solutions in order.
If you are using Linux on a Cherry Trail device (e.g., Chuwi Hi10/Hi12), the ACPI code needs to configure interrupts and memory for the LPE audio engine. Intel provides a proprietary driver ( iaLPSS_I2C
Go to the official support site for your specific device model. Search for "SD Host Controller" or "Chipset Drivers." Download and run the installer. Detailed Driver Information for ACPI\80860F14
The ACPI driver binding for this ID requires specific handling because the Bay Trail I2C controllers are not fully compliant with the standard Synopsys DesignWare I2C IP block. They need a "semaphore" mechanism to coordinate with the P-unit (Power Management unit).
Install any optional updates, as the driver might be listed there. Method 2: Manually Install Driver via Device Manager Key Details The ACPI\80860F14 device is a critical
The hardware ID (often expanded as ACPI\VEN_8086&DEV_0F14 ) maps directly to the Intel SD Host Controller . This specific hardware string identifies a critical system component responsible for managing low-level storage interfaces. It handles built-in eMMC internal flash storage and physical MicroSD card expansion slots on devices powered by older Intel architectures. These setups are common in Intel Bay Trail, Braswell, and Cherry Trail low-power chipsets.
