The ASUS ASMedia XHCI Controller driver enables Windows to communicate with the ASMedia USB controller used on compatible ASUS hardware. It helps connected USB devices work through the ports managed by that controller. When downloading a driver for Windows 11, 10, 8, or 7, choose a package that matches your ASUS model and Windows version, since compatibility varies by release.

Key Features

• USB controller recognition: Helps Windows identify and configure the ASMedia XHCI controller correctly in Device Manager.
• Peripheral connectivity: Supports communication with compatible USB devices, including external drives, keyboards, mice, and USB hubs.
• USB transfer support: Enables the controller’s supported USB functions and transfer modes. Actual speeds depend on the controller, connected device, cable, and port.
• Compatibility and stability fixes: An appropriate driver update may address connection problems, device detection issues, or controller errors covered by that release.

How to Install

1. Identify your hardware and Windows version. Check your ASUS motherboard or computer model, then confirm your Windows edition and whether it uses a 32-bit or 64-bit architecture. If needed, use the controller’s Hardware IDs in Device Manager to verify compatibility.

1. Choose the matching driver package. Review the supported models and operating systems before downloading. A package intended for Windows 7 or 8 should not be assumed suitable for Windows 10 or 11; newer Windows versions may already use a compatible built-in driver.

1. Prepare for installation. Save your work, close open applications, and extract the download if it is compressed. Safely disconnect external storage connected through the affected controller, as USB connectivity may briefly stop during installation.

1. Install the driver. Run the included setup program with administrator permissions and follow its instructions. If the package provides driver files without an installer, open Device Manager, locate the controller, select Update driver, and browse to the extracted folder.

1. Restart and check operation. Reboot if prompted, then confirm that the controller appears without a warning icon in Device Manager. Test a USB device on one of its ports. If a new problem appears after updating, use Roll Back Driver when available or reinstall the previous compatible package.

Common Issues and Fixes

• Install fails or rolls back: Uninstall the existing USB xHCI controller in Device Manager, check “Delete the driver software,” reboot, then run the ASUS/ASMedia installer as administrator. Disconnect USB peripherals during install.
• Controller or ports not detected: Enable xHCI Hand-off/USB 3.x in BIOS, reseat the card or header, and test another port. In Device Manager, enable “Show hidden devices” and scan for hardware changes.
• Version conflicts after Windows Update: Windows may replace the ASMedia driver with its inbox xHCI driver. Roll back to the ASUS package in Device Manager, or reinstall the matching ASMedia version and pause automatic driver updates.
