Intel ICH9 Family USB 2.0 Enhanced Host Controller 293A Driver

The Intel ICH9 Family USB 2.0 Enhanced Host Controller 293A driver helps Windows recognize and manage the USB 2.0 controller built into compatible Intel ICH9-based systems. It is relevant when troubleshooting an unrecognized controller, USB connection problems, or missing device information after reinstalling Windows. Although USB printers can connect through this controller, it is a chipset component—not a printer driver—and printers may require separate software.

Key Features

• USB controller recognition: Helps Windows identify the Intel ICH9 USB 2.0 Enhanced Host Controller and associate it with the appropriate system driver.
• High-speed USB support: Enables compatible USB 2.0 devices to use the controller’s high-speed capabilities when the hardware and operating system support them.
• Peripheral connectivity: Supports the underlying USB connection used by devices such as printers, scanners, and external storage.
• System integration: Works with Windows USB components; depending on your system, the required support may already be included in Windows rather than supplied as a separate Intel download.

How to Install Intel ICH9 Family USB 2.0 Enhanced Host Controller 293A Driver

1. Check your device and Windows version. Open Device Manager and look under Universal Serial Bus controllers or Other devices. Check the controller’s hardware IDs in Properties to confirm the Intel device identifier 293A, then verify your Windows version and architecture.
2. Choose a compatible source. For an Intel ICH9 Family USB 2.0 Enhanced Host Controller 293A driver download for Windows, check Windows Update or your computer or motherboard manufacturer’s support resources first. Look for a free download that explicitly supports your hardware and operating system.
3. Review compatibility before downloading. For Windows 11, 10, 8, or 7, use only a package documented for your configuration. Older ICH9 systems may lack manufacturer-supported Windows 10/11 packages; a newer operating system does not guarantee compatibility.
4. Install the appropriate package. If an installer is provided, follow its instructions. For an extracted driver package, use Device Manager’s Update driver option and browse to the folder. Do not force an incompatible driver.
5. Restart and test. Restart if requested, check Device Manager for warnings, and test your USB devices. If only a printer fails, check its dedicated driver and cable as well.

Keep your system updated through trusted sources, and choose the latest version approved for your specific configuration. An update may help resolve documented issues, but a working controller does not necessarily need a separate download or replacement driver.

Common Issues and Fixes

• Install fails or Code 10/28/39 in Device Manager: The ICH9 EHCI controller normally uses Microsoft’s inbox USB 2.0 Enhanced Host Controller driver. Uninstall the device, check “Delete driver software,” reboot, and rescan. Install only the Intel Chipset Device Software/INF for your board—not an unrelated Intel USB package.
• Device not detected / USB 2.0 ports dead: Check BIOS for EHCI Hand-off and USB Legacy support, verify front-panel USB headers, and test rear ports. In Device Manager, scan for hardware changes; if still missing, reset BIOS defaults and power-cycle.
• Version conflicts after chipset/OEM updates: Remove hidden USB controller entries, roll back the previous EHCI driver, and avoid overlapping Intel and motherboard-vendor USB drivers. Let Windows select the compatible EHCI driver.
