Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 Driver

The Intel(R) 82801DB/DBM USB Universal Host Controller – 24C2 driver lets Windows communicate with a legacy USB controller found in systems using Intel 82801DB/DBM chipsets. It supports basic USB connectivity for devices such as keyboards and mice, and is relevant when reinstalling Windows or troubleshooting a missing controller driver in Device Manager. Although the hardware is Intel-based, the driver provider listed for this device is Microsoft.

Key Features

• USB controller support: Enables Windows to manage the controller’s USB 1.1 functions and communicate with compatible low- and full-speed USB peripherals.
• Microsoft driver integration: Works with Windows USB components to handle device connections and routine data transfers.
• Device recognition: Can resolve a missing-driver warning when the correct driver is installed; hardware faults or other USB issues may require separate troubleshooting.
• Legacy Windows coverage: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Individual driver packages may support only some of these versions, so check compatibility before downloading.

How to Install Intel(R) 82801DB/DBM USB Universal Host Controller – 24C2 Driver

1. Confirm the controller. Open Device Manager and locate the controller under Universal Serial Bus controllers or Other devices. Check Properties > Details > Hardware IDs to verify that the device identifier includes `VEN_8086&DEV_24C2`.
2. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed here, but Windows 11 compatibility is not confirmed.
3. Choose a compatible source. Before selecting an Intel(R) 82801DB/DBM USB Universal Host Controller – 24C2 driver download for Windows, try Windows Update. If using a free download package, verify its source, supported operating systems, and hardware IDs.
4. Install the driver. Extract the package if needed. In Device Manager, right-click the controller, select Update driver or the equivalent option, and browse to the extracted driver folder. Avoid forcing installation if Windows reports incompatibility.
5. Restart and test. Restart if prompted, then check Device Manager for warnings and test a known-working USB peripheral.

Keep the driver updated through Windows Update or a verified, compatible package. The latest version is useful only if it supports your hardware and Windows release; a working legacy driver does not necessarily need an update simply because another package has a higher version number.
