Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 Driver

The Intel(R) 82801DB/DBM USB Universal Host Controller – 24C7 driver helps Windows communicate with the USB host controller built into older Intel chipset-based computers. It supports basic USB connectivity for devices such as keyboards and mice, and is relevant when you reinstall Windows, troubleshoot missing USB ports, or see a warning beside this controller in Device Manager.

Key Features

• USB controller support: Enables Windows to manage the controller’s USB 1.1 connections and communicate with compatible low- and full-speed USB peripherals.
• Device recognition: Helps Windows identify the controller correctly rather than display it as an unknown device when the appropriate driver is missing.
• Microsoft-provided driver integration: This controller uses Microsoft USB driver components supplied with compatible Windows installations; a separate downloadable installer may not be necessary.
• Legacy system compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Actual availability depends on the computer, Windows architecture, and the driver package.

How to Install Intel(R) 82801DB/DBM USB Universal Host Controller – 24C7 Driver

1. Confirm your hardware. Open Device Manager and locate the controller under Universal Serial Bus controllers or Other devices. Check its hardware IDs in Properties to verify that the entry matches the 24C7 controller.
2. Check your Windows version. Confirm whether your installation is 32-bit or 64-bit. For Windows 10/11 systems, do not assume compatibility: Windows 10 is listed here, but Windows 11 support is not established.
3. Look for the appropriate driver. Start with Windows Update or your computer manufacturer’s support resources. Before choosing an Intel(R) 82801DB/DBM USB Universal Host Controller – 24C7 driver download for Windows, verify its source and compatibility. A free download should not require a paid driver-updater subscription.
4. Install or update the driver. In Device Manager, right-click the controller, select Update driver, and search automatically. If you have a verified extracted package, choose the option to browse your computer and select its folder.
5. Restart and test. Restart if prompted, then reconnect a USB device and check whether the controller’s warning icon has cleared. Avoid uninstalling an active USB controller unless you have another way to control the computer.

Keep the driver updated through trusted Windows or manufacturer channels. The latest version is not necessarily a newer standalone download for this legacy controller; use the most recent compatible driver, and avoid replacing a working installation with an unverified package.
