The ASUS USB/MIR Rev. 1.11 is a legacy expansion bracket designed for older ASUS motherboards to provide additional USB 1.1 ports and a proprietary Infrared (MIR) connection. Because it is a passive hardware component rather than a standalone device, it does not have a "verified" driver of its own. Driver & Support Overview Plug-and-Play (USB): The USB ports on this bracket rely on the motherboard's built-in USB Host Controller drivers. On modern operating systems like Windows 10 and 11, these drivers are automatically installed during the OS setup. Infrared (MIR) Support: The MIR (Medium Infrared) functionality was intended for much older operating systems (Windows 98/ME/2000) and is generally not supported by modern Windows versions. Verification: Official verification of ASUS hardware functionality can be checked via the Device Manager under the "Universal Serial Bus controllers" category. Troubleshooting & Manual Setup If the USB ports on your Rev. 1.11 bracket are not working: Motherboard Compatibility: This bracket was designed for specific legacy ASUS pinouts. Using it on modern motherboards with standard USB 2.0 headers may result in "USB device not recognized" errors without hardware modification (e.g., removing specific capacitors C2-C5). BIOS Settings: Ensure that USB legacy support is enabled in your BIOS. You can access these settings by pressing F2 or Del during startup. Driver Reinstallation: Open the Windows Device Manager . Find the USB Host Controller or Root Hub . Right-click and select Uninstall device , then restart your computer to force a fresh driver installation. Official Downloads: For general motherboard utilities that might assist with port detection, visit the ASUS Download Center and enter your specific motherboard model name. Are you trying to connect a specific infrared device to this bracket, or are you just trying to get the USB ports to work on a modern PC?
The ASUS USB/MIR REV 1.11 is a legacy motherboard expansion bracket designed to provide additional connectivity by adding two USB ports to a desktop system. Because this hardware is a passive physical bridge between the motherboard's internal headers and external ports, it generally does not require a specific standalone driver to function. Instead, it relies on the Universal Serial Bus (USB) controller drivers already integrated into your operating system or provided by your motherboard's chipset. Driver Verification and Installation If you are experiencing issues with the ports on this bracket, follow these steps to verify and update the necessary drivers: Chipset Drivers : Visit the ASUS Download Center and enter your motherboard model name . Download and install the latest Chipset or Board Support Package (BSP) , which includes essential connectivity drivers for all onboard USB headers. Device Manager Check : Right-click the Start button and select Device Manager . Expand the Universal Serial Bus controllers section to ensure there are no yellow warning icons. Automatic Reinstallation : If a port is not working, right-click the USB Host Controller in Device Manager, select Uninstall device , and restart your computer. Windows will automatically reinstall the verified driver upon reboot. BIOS Settings : Ensure that USB functions are enabled in your BIOS. You can typically access this by holding F2 or Del during startup. Hardware Connectivity Internal Connection : The REV 1.11 bracket must be securely connected to the correct 10-pin USB header on the motherboard. Legacy Support : While this bracket was common on older ASUS motherboards, it remains compatible with modern versions of Windows (10 and 11) because it adheres to standard USB signaling protocols.
