The Broadcom Serial Bus Driver over UART Bus Enumerator helps Windows identify and manage compatible Broadcom hardware connected through a UART serial interface. It provides the bus-enumeration support that allows Windows to recognize associated devices and load their corresponding drivers. For Windows 11, 10, 8, or 7, choose a package that matches both your computer’s hardware and operating system.

Key Features

• UART device detection: Enables Windows to enumerate supported Broadcom components connected through the system’s UART bus.
• Driver coordination: Helps Windows associate detected hardware with the appropriate device drivers. Additional drivers may still be required for functions such as Bluetooth.
• Device Manager integration: Allows compatible hardware to be identified and managed in Windows, helping resolve missing-driver entries when the correct package is installed.
• Hardware-specific support: Provides the connection layer required by certain Broadcom implementations. Compatibility depends on your computer model and the driver package, not just the Windows version.

How to Install

1. Check your system details. Confirm whether you are running Windows 11, 10, 8, or 7 and check your system architecture. In Device Manager, review the affected device’s Properties and Hardware Ids if you need to verify compatibility.

1. Select a matching driver package. Use a Broadcom Serial Bus Driver over UART Bus Enumerator package approved for your computer model and Windows version. Prefer the computer manufacturer’s recommended release, especially for laptops and tablets with integrated wireless hardware.

1. Prepare the downloaded files. Extract the package if it is compressed, and review any included installation instructions. Creating a restore point before changing drivers can make it easier to undo an unsuccessful update.

1. Install the driver. Run the included setup program if available. For a manual installation, open Device Manager, right-click the relevant device, select Update driver, and choose the option to browse your computer for drivers. Point Windows to the extracted folder.

1. Restart and verify detection. Restart your computer if prompted, then check Device Manager for warning icons. If the device remains unidentified, confirm the hardware ID and package compatibility rather than forcing an unrelated driver. Any associated Bluetooth or wireless function may need its own matching driver before it works.

Common Issues and Fixes

• Install fails or rolls back: Confirm you’re using the INF matching your platform (x64/ARM64) and Windows build. Install chipset/Serial IO and ACPI drivers first; missing UART/ACPI dependencies can block the Broadcom enumerator. If signature enforcement blocks it, use the vendor-signed package.
• Device not detected: Check BIOS/UEFI that the UART/serial bus is enabled and not in a conflicting mode. In Device Manager, look under System devices for “Broadcom Serial Bus Driver over UART Bus Enumerator”; scan for hardware changes after enabling.
• Version/conflict errors: Remove older Broadcom serial bus/UART packages and reboot before installing. Avoid mixing Windows Update and OEM packages; use the OEM version for your device model.
