The Broadcom BCM20702 Bluetooth 4.0 USB Device driver helps Windows recognize the adapter and communicate with nearby Bluetooth accessories. Installing a compatible driver can resolve detection problems and enable wireless connections to devices such as keyboards, mice, headsets, and phones.

Key Features

• Bluetooth adapter recognition: Provides the software support Windows needs to identify and operate the Broadcom BCM20702 USB Bluetooth hardware.
• Wireless accessory connectivity: Supports pairing and communication with compatible Bluetooth peripherals, with available functions depending on the accessory and Windows Bluetooth services.
• Bluetooth 4.0 support: Enables the adapter’s Bluetooth capabilities, including low-energy connections where supported by the operating system, driver, and connected device.
• Connection troubleshooting: Replacing a missing, damaged, or incompatible driver may help address pairing failures, unavailable Bluetooth settings, or adapter errors in Device Manager.

How to Install

1. Confirm the adapter and Windows version. Open Device Manager and look under Bluetooth or Other devices for the Broadcom BCM20702 Bluetooth 4.0 USB Device. Check whether your system runs Windows 11, 10, 8, or 7, and confirm its architecture before selecting a package.

1. Choose a compatible driver. Download a Broadcom driver package that explicitly supports your adapter and Windows version. Packages supplied for a particular computer or USB adapter may not work with every BCM20702-based device, so compare hardware IDs if compatibility is unclear.

1. Prepare the downloaded files. Extract the package if it is compressed. Close active Bluetooth applications and save your work, as installation may temporarily disconnect paired accessories.

1. Install the driver. Run the included installer and follow its prompts. If no installer is provided, right-click the adapter in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Restart and test Bluetooth. Restart the computer if prompted, then check that the adapter appears without a warning icon. Enable Bluetooth in Windows settings or Control Panel and pair an accessory to verify operation.

Driver availability and Bluetooth features can differ across Windows 11, 10, 8, and 7. Do not assume an older package supports a newer system; if installation fails, check Windows Update or the computer or adapter manufacturer for a suitable release.

Common Issues and Fixes

• Install fails or stalls: Uninstall any existing Broadcom/WIDCOMM Bluetooth stack and OEM Bluetooth driver, remove the BCM20702 in Device Manager with “Delete driver software,” reboot, then run the package as administrator.
• Device not detected: Use a direct rear USB port or reseat the internal module, enable Bluetooth/USB in BIOS, disable USB selective suspend, and show hidden devices in Device Manager to check for a failed BCM20702 entry.
• Version conflicts or Code 10/43: Roll back or update the driver, manually select the Broadcom BCM20702 driver via “Have Disk,” remove duplicate Bluetooth radios, and restart the Bluetooth Support Service. Avoid mixing OEM and generic packages.
