Intel ICH9 Family USB2 Enhanced Host Controller 293A Driver

The Intel ICH9 Family USB2 Enhanced Host Controller 293A driver helps Windows communicate with the USB 2.0 controller built into Intel ICH9-based systems. It is relevant when troubleshooting missing USB controller entries, Device Manager warnings, or problems connecting USB peripherals. Despite sometimes being listed under Audio, this device is a USB host controller—not a dedicated sound device.

Key Features

• USB 2.0 connectivity: Supports communication between the host controller and compatible peripherals, including storage devices, keyboards, printers, and USB audio equipment.
• Device recognition: Helps Windows identify and configure the controller correctly when the appropriate system drivers and chipset information are installed.
• System integration: Works with Windows USB components to manage connected devices and controller resources.
• Troubleshooting support: Restoring the correct driver configuration may resolve controller-related errors, although faulty cables, ports, or peripherals require separate checks.

How to Install Intel ICH9 Family USB2 Enhanced Host Controller 293A Driver

1. Confirm the device. Open Device Manager and locate the controller under Universal Serial Bus controllers or Other devices. Check Properties > Details > Hardware Ids for `PCIVEN_8086&DEV_293A` to help verify the match.
2. Check compatibility. Before choosing an Intel ICH9 Family USB2 Enhanced Host Controller 293A driver download for Windows, confirm your Windows version and system architecture. For Windows 11, 10, 8, or 7, availability depends on your computer model and the package offered; a listing alone does not establish compatibility.
3. Choose a trusted source. Start with Windows Update or your computer manufacturer’s support resources. Windows often supplies the USB controller driver itself, while Intel chipset packages may primarily provide device identification information. Choose a free download from an official source rather than a paid driver updater.
4. Install the appropriate package. If your manufacturer provides a compatible installer, follow its instructions. For an extracted driver package, use Device Manager > Update driver > Browse my computer for drivers, then select the folder.
5. Restart and test. Reboot if prompted, check for Device Manager warnings, and reconnect your USB devices. If problems began after an update, consider the Roll Back Driver option when available.

Keep your controller configuration current through Windows Update and manufacturer-supported releases. The latest version is useful only if it matches your hardware and operating system; avoid forcing older packages onto Windows 10/11. If USB devices already work reliably, a separate manual driver update may not be necessary.

Common Issues and Fixes

• Install fails or says driver is not for this platform: Verify Windows version/architecture and use the Intel chipset/INF package matching ICH9; run setup as administrator. Do not force a generic USB driver onto the Intel 293A controller.
• Device not detected / yellow warning mark: Enable USB legacy support and EHCI hand-off in BIOS, reseat front-panel/USB headers, then scan for hardware changes. Install the chipset INF before the USB2 Enhanced Host Controller driver.
• Version conflict with Windows’ built-in EHCI driver: Avoid replacing the inbox USB2 driver with an older Intel package. Roll back in Device Manager or uninstall with “delete driver,” rescan, and install only the ICH9-compatible Intel release.
