Intel(r) 82371AB/EB PCI-zu-USB universeller Hostcontroller Driver

The Intel(r) 82371AB/EB PCI-zu-USB universeller Hostcontroller driver lets Windows communicate with the USB host controller found in certain older Intel-based systems and virtual machines. It helps the operating system manage devices connected through this legacy USB interface and is relevant when Device Manager shows a missing controller driver, a warning icon, or an unrecognized USB controller.

Key Features

• Legacy USB controller support: Enables Windows to recognize and operate the Intel 82371AB/EB PCI-to-USB host controller, which uses the UHCI interface for USB 1.1 connections.
• Windows USB integration: Works with the operating system’s USB components to support compatible peripherals, including keyboards and mice.
• Microsoft-provided driver support: This listing identifies Microsoft as the driver vendor, although the controller hardware is Intel-based. A suitable driver may already be included with Windows.
• Compatibility guidance: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Match the package to your Windows version and architecture; listed support does not guarantee that every package works on every system.

How to Install Intel(r) 82371AB/EB PCI-zu-USB universeller Hostcontroller Driver

1. Identify the controller. Open Device Manager and locate the host controller under Universal Serial Bus controllers or Other devices. Check its hardware IDs in Properties to confirm that the driver matches your device.
2. Check your Windows version. Confirm whether your installation is 32-bit or 64-bit. For Windows 10/11 systems, verify compatibility carefully: Windows 10 is listed here, but Windows 11 support is not established.
3. Choose a trusted source. Before selecting an Intel(r) 82371AB/EB PCI-zu-USB universeller Hostcontroller driver download for Windows, check Windows Update or your computer manufacturer’s support resources. If choosing a free download, verify its source and digital signature.
4. Install the matching driver. Use Device Manager’s Update Driver option to search automatically, or browse to the extracted driver folder. Follow the prompts and avoid forcing an incompatible package.
5. Restart and test. Restart if prompted, then confirm that Device Manager reports normal operation. Test a compatible USB peripheral connected through the controller.

Keep the driver updated through trusted channels, but prioritize compatibility over a higher version number. The latest version suitable for this legacy controller may be an older Microsoft driver; an update will not add USB 2.0 or USB 3.x capabilities. If the controller works reliably, avoid replacing its driver without a clear reason.
