Controlador de host universal USB de la familia Intel(R) ICH9 - 2939 Driver

The Controlador de host universal USB de la familia Intel(R) ICH9 – 2939 driver helps Windows recognize and manage the USB universal host controller built into Intel ICH9-family chipsets. It is relevant to older desktop and laptop systems where this controller appears in Device Manager with a warning, an unrecognized-device entry, or USB connectivity problems.

Key Features

• Controller identification: Helps Windows identify the Intel ICH9 USB controller associated with device ID 2939 and associate it with the appropriate system driver.
• Legacy USB support: Enables the controller’s role in handling low- and full-speed USB devices, such as compatible keyboards, mice, and other peripherals.
• System integration: Works with Windows USB components to support device detection and communication. Depending on the operating system, the required support may already be included in Windows.
• Compatibility-focused setup: Intended for matching Intel ICH9 hardware, with package selection based on your Windows version and system architecture—not simply the newest available release.

How to Install Controlador de host universal USB de la familia Intel(R) ICH9 – 2939 Driver

1. Confirm the hardware. Open Device Manager and locate the controller under Universal Serial Bus controllers or Other devices. Check Properties > Details > Hardware IDs for Intel vendor ID VEN_8086 and device ID DEV_2939.
2. Check your operating system. Download listings may cover Windows 10, 8.1, 7, Vista, and XP, but individual packages can support only a subset. Choose the correct 32-bit or 64-bit package. For Windows 10/11 systems, do not assume that Windows 10 compatibility also means Windows 11 support.
3. Select a trusted package. Before choosing a Controlador de host universal USB de la familia Intel(R) ICH9 – 2939 driver download for Windows, verify its source and compatibility notes. Prefer your computer manufacturer, Intel support resources, or Windows Update when available. A free download should not require a paid driver-updater subscription.
4. Install the driver. Create a restore point if available, then run the supplied installer. If the package contains driver files without an installer, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and test. Restart Windows if prompted, check that the controller has no warning icon, and test your USB peripherals. Updating a host controller may temporarily interrupt connected USB devices.

Keep the driver updated when a compatible update addresses a specific issue or is recommended by your system manufacturer. The latest version is useful only if it supports your hardware and operating system; avoid replacing a working Windows driver with an incompatible legacy package.
