Intel 82801DB DBM USB Universal Host Controller 24c2 Driver

The Intel 82801DB DBM USB Universal Host Controller 24c2 driver helps Windows communicate with the USB controller built into older Intel chipsets, enabling connected USB peripherals to function correctly. It is relevant when you are restoring a legacy PC, troubleshooting unrecognized USB devices, or checking a controller warning in Device Manager. Despite being listed under Audio, this device is a USB host controller rather than a sound card.

Key Features

• USB controller recognition: Helps Windows identify and configure the Intel controller associated with hardware ID `PCIVEN_8086&DEV_24C2`.
• Legacy peripheral support: Provides the controller support needed for compatible USB devices, such as keyboards, mice, and other low-bandwidth peripherals.
• Windows integration: Works with the operating system’s USB stack; depending on your Windows release, the appropriate driver may already be included.
• Troubleshooting assistance: Installing the correct matching driver can resolve missing-driver warnings, though it will not fix damaged ports or incompatible hardware.

How to Install Intel 82801DB DBM USB Universal Host Controller 24c2 Driver

1. Confirm the device identity. Open Device Manager, locate the USB controller or unknown device, and select Properties > Details > Hardware Ids. Check for `VEN_8086&DEV_24C2` before choosing a package.

1. Check your Windows version. Before selecting an Intel 82801DB DBM USB Universal Host Controller 24c2 driver download for Windows, verify your operating system and whether it is 32-bit or 64-bit. For Windows 11, 10, 8, or 7, confirm compatibility individually rather than assuming one legacy package supports them all. Windows 10/11 compatibility is not guaranteed for this older hardware.

1. Choose a trustworthy source. Try Windows Update or your computer manufacturer’s support resources first. If a free download is available, check its supported hardware and operating systems. The latest version is useful only if it matches your system.

1. Install the matching driver. Run the supplied installer, or select Update driver > Browse my computer for drivers in Device Manager and point Windows to the extracted files. Do not force-install an incompatible package.

1. Restart and test. Restart if prompted, then check Device Manager for warnings and test a known-working USB peripheral.

Keep the driver updated through trusted sources, but avoid replacing a working Windows-provided driver simply because another package is labeled newer. An update should address a relevant issue or explicitly support your hardware and Windows version.

Common Issues and Fixes

• Install fails with unsigned or incompatible driver: Windows 10/11 may block older Intel .inf packages. Use Device Manager → Update driver → Browse → Let me pick → Have Disk, or temporarily disable driver signature enforcement. Prefer the inbox USB UHCI driver if present.
• Controller not detected: Check BIOS for “USB 1.1/UHCI” or legacy USB support enabled. Install the Intel chipset INF first. In Device Manager, look for `PCIVEN_8086&DEV_24C2` under Other Devices; if missing, rescan hardware.
• Version conflict / yellow bang: Remove any third-party driver-updater USB driver. Roll back to Microsoft’s generic UHCI driver or reinstall Intel chipset drivers matching the 82801DB (ICH4) platform. Avoid forcing newer USB 2.0/3.0 drivers.
