, a component typically found in Intel Atom "Bay Trail" and "Cherry Trail" systems. This controller is essential for managing eMMC internal storage and MicroSD card slots. Home Assistant Community Quick Fix Guide

If you see this as an "Unknown Device" in Device Manager, follow these steps to install the correct driver: 1. Check Windows Update Before manual installation, try letting Windows find it: Right-click the button and select Device Manager Acpi 80860f14

Find the device under "Other devices" (usually listed with a yellow exclamation mark). Right-click it and select Update driver Search automatically for updated driver software 2. Manual Driver Installation

If Windows Update fails, you can download the driver manually from your device manufacturer (OEM) support page. Common systems using this ID include: : Models like the Steps for Manual Install: Download the Intel Serial IO Driver Intel SD Host Controller Driver for your specific laptop model. Extract the ZIP file. Device Manager , right-click the unknown device and choose Browse my computer for drivers Point it to the extracted folder and click 3. Advanced: Linux Troubleshooting The hardware ID ACPI\80860F14 refers to the Intel

On Linux systems (e.g., Ubuntu, Mint), this hardware is often handled by the sdhci_acpi kernel module. Update Kernel : Ensure you are running kernel 5.19 or later for the best support.

4. Driver Support by Operating System

"Is this a hardware failure?"

No. The presence of ACPI\80860F14 in Device Manager does not indicate a broken component. It indicates a missing or corrupted driver. The physical I2C controller is integrated into the Intel SoC and is almost certainly functional.

Bay Trail and Cherry Trail Architectures

Between 2013 and 2016, Intel released the Bay Trail (e.g., Atom Z3700 series, Celeron N2800/J1900) and later Cherry Trail (Atom x5/x7) platforms. These system-on-chips (SoCs) were designed for tablets, low-cost laptops, and embedded devices. To save power and physical space, Intel moved many peripheral controllers—such as I2C, SPI, and UART—onto the SoC itself, exposing them via ACPI instead of traditional PCIe.

The I2C controller is a two-wire serial bus used to connect low-speed peripherals like:

• Touchscreens
• Touchpads
• Ambient light sensors
• Accelerometers (for screen rotation)
• GPIO expanders
• Camera sensors

Each I2C controller on the SoC gets a unique ACPI ID. The specific ID 80860F14 typically refers to I2C controller #5 or #6 on the Intel Low Power Subsystem (LPSS).

4.1. Linux

• Driver: i2c_designware_platform
• Kernel Config: CONFIG_I2C_DESIGNWARE_PLATFORM
• ACPI Matching: The driver matches against "80860F14", 0 in drivers/i2c/busses/i2c-designware-platdrv.c
• Common Issues: Failure to probe due to missing device_property definitions (clock frequency, IRQ mapping). Often requires firmware patches or dmi_system_id quirks.
