Intel(R) 82801CA/CAM USB Universal Host Controller - 2484 Driver

The Intel(R) 82801CA/CAM USB Universal Host Controller – 2484 driver lets Windows communicate with the legacy USB host controller built into compatible Intel chipsets. It supports basic USB connectivity and may be needed when reinstalling Windows, troubleshooting unrecognized peripherals, or resolving a controller warning in Device Manager.

Key Features

• Legacy USB support: Enables Windows to manage the controller’s USB 1.1 connections for compatible devices such as keyboards, mice, and other low-bandwidth peripherals.
• Windows integration: Works with the operating system’s USB driver stack to handle device detection and communication. The Microsoft vendor listing refers to the Windows driver provider, rather than the chipset manufacturer.
• Controller identification: Helps Windows recognize this specific Intel controller instead of leaving it listed as unknown hardware.
• Compatibility-focused setup: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package’s supported Windows edition and architecture before installing; a single package may not cover every listed system.

How to Install Intel(R) 82801CA/CAM USB Universal Host Controller – 2484 Driver

1. Confirm your hardware. Open Device Manager and locate the controller under Universal Serial Bus controllers or Other devices. Check Properties > Details > Hardware IDs to confirm that the download matches your device.
2. Check your Windows version. Verify whether your system uses 32-bit or 64-bit Windows. If comparing Windows 10/11 options, note that Windows 11 is not included in this device’s listed OS support.
3. Choose a compatible source. For an Intel(R) 82801CA/CAM USB Universal Host Controller – 2484 driver download for Windows, start with Windows Update or your computer manufacturer’s support resources. If choosing a free download elsewhere, verify its source and compatibility before proceeding.
4. Install the driver. Run the supplied installer if available. For an extracted driver package, right-click the controller in Device Manager, select Update driver, and browse to the folder containing the matching driver files.
5. Restart and test. Restart if prompted, then reconnect a USB peripheral and check Device Manager for remaining warnings. Keep an alternative input method available if troubleshooting affects your USB keyboard or mouse.

Keep the driver updated through trusted sources, but choose the latest version compatible with your hardware and Windows release—not simply the newest package available. An update may help resolve driver-related issues, but it cannot upgrade this legacy controller to USB 2.0 or newer speeds.
