The ASMedia USB Root Hub driver helps Windows communicate with the root hub associated with an ASMedia USB controller, allowing the system to manage connected USB devices. Although listed under Printer, this component is part of the USB subsystem rather than a printer-specific driver; it can support the USB connection used by a printer but does not replace the printer’s own software.

Key Features

• USB device communication: Supports communication between Windows and peripherals connected through the ASMedia controller, such as printers, storage devices, and input devices.
• Port and connection management: Helps the operating system detect connected hardware and manage the USB ports associated with the root hub.
• Power management support: Works with Windows to manage USB device power states, including suspend and resume where supported by the hardware and driver.
• Windows compatibility: Driver packages may be available for Windows 11, 10, 8, and 7. Compatibility depends on the specific controller, computer model, and package, so verify support before downloading.

How to Install

1. Identify the hardware and Windows version. Open Device Manager and look under Universal Serial Bus controllers for the ASMedia USB Root Hub or its associated controller. Check your Windows version and whether your system requires a 32-bit or 64-bit package.

1. Choose a matching driver. Use the manufacturer’s package intended for your computer, motherboard, or ASMedia controller. Confirm that it supports your installed operating system; a package for Windows 7 is not necessarily suitable for Windows 11.

1. Prepare for installation. Save your work and safely disconnect USB storage devices if needed. Updating the USB controller software can temporarily interrupt connected peripherals, including a USB keyboard or mouse.

1. Run the installer or update manually. Extract the download if necessary, then follow the included setup instructions. If the package provides driver files without an installer, use Device Manager, right-click the relevant device, select Update driver, and browse to the extracted folder. The root hub driver may be included in a broader USB controller package.

1. Restart and test your devices. Restart Windows if prompted, then check Device Manager for warning icons. Reconnect your peripherals and confirm they work normally. If a printer still cannot print, check its printer-specific driver and connection settings separately.

Common Issues and Fixes

• Install fails or rolls back: Use the ASMedia package for your exact Windows version and run it as administrator. Remove existing ASMedia USB host/root hub entries in Device Manager, choosing “Delete the driver software,” reboot, then reinstall. Avoid forcing an unsigned or generic xHCI driver.
• Root hub/ports not detected: Confirm xHCI/USB 3.0 is enabled in BIOS, power-cycle the PC, then scan for hardware changes. In Device Manager, uninstall “Unknown USB Device” or the affected root hub and restart so Windows re-enumerates it.
• Version conflicts, Code 10 or 43: Roll back or uninstall conflicting ASMedia USB drivers, then install the latest WHQL package. Do not mix OEM and Microsoft generic root hub drivers; disable USB selective suspend if the hub drops after sleep.
