Intel 82801EB USB Universal Host Controller 24D2 Driver

The Intel 82801EB USB Universal Host Controller 24D2 driver helps Windows communicate with the USB controller built into Intel’s older 82801EB chipset. It is relevant when restoring a legacy PC, investigating an unrecognized USB controller in Device Manager, or troubleshooting connected USB devices. Despite sometimes appearing in an Audio category, this device is a USB host controller, not a sound card.

Key Features

• USB controller recognition: Helps Windows identify the controller correctly and associate it with the appropriate system driver.
• Legacy USB support: Enables communication with compatible low- and full-speed USB peripherals, such as keyboards and mice, through the controller’s USB 1.1 interface.
• System integration: Works with Windows USB components to manage connected devices; individual peripherals may still require their own drivers.
• Hardware-specific matching: The controller identifier helps distinguish this device from other Intel USB controllers when checking driver compatibility.

How to Install Intel 82801EB USB Universal Host Controller 24D2 Driver

1. Confirm the hardware. Open Device Manager, locate the USB controller or unidentified device, and select Properties > Details > Hardware Ids. Check for `PCIVEN_8086&DEV_24D2` before choosing a package.
2. Check Windows compatibility. Before choosing an Intel 82801EB USB Universal Host Controller 24D2 driver download for Windows, verify support for your Windows 11, 10, 8, or 7 installation and its architecture. This legacy controller does not imply official Windows 10/11 support; a Windows-provided driver may be the appropriate option.
3. Use a trusted source. Start with Windows Update or your PC manufacturer’s support resources. Choose the latest version explicitly compatible with your hardware and operating system. A free download should not require purchasing a separate driver-update utility.
4. Install the supported driver. If a compatible package includes an installer, follow its instructions. For an extracted driver package, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder. Do not force an incompatible driver.
5. Restart and test. Restart if prompted, then check Device Manager for warning icons and test a USB keyboard, mouse, or another known-working peripheral.

Keep the driver updated through trusted support channels, but prioritize compatibility over version numbers. If the controller already works reliably with the Windows-provided driver, a manual update may not be necessary. If problems begin after an update, use Roll Back Driver when available.

Common Issues and Fixes

• Install fails or driver won’t load: The 82801EB UHCI driver is legacy and may be unsigned or blocked on modern Windows. Use Device Manager > Update driver > Browse to the extracted Intel INF, and temporarily disable driver signature enforcement if needed. Confirm 32/64-bit match.
• Controller not detected: Verify the UHCI function is enabled in BIOS and install the Intel chipset INF so the PCI device enumerates. Try another USB 1.1 port, avoid hubs, and remove/rescan the device if it shows Code 10 or 43.
• Version conflicts: Multiple UHCI controllers may bind to different INF versions. Uninstall conflicting USB host controller entries, reboot, and let Windows re-enumerate; avoid mixing generic and Intel drivers.
