Broadcom BCM20702 Bluetooth USB Device Driver

The Broadcom BCM20702 Bluetooth USB Device driver lets Windows recognize the adapter and communicate with compatible Bluetooth peripherals, such as mice, keyboards, and headsets. It is useful when Bluetooth is missing from your PC, the adapter appears as an unknown device, or an existing connection stops working after a system change.

Key Features

• Bluetooth adapter recognition: Provides the software Windows needs to identify and use the Broadcom BCM20702 USB device.
• Peripheral connectivity: Enables pairing with compatible Bluetooth accessories, with available functions depending on the accessory and Bluetooth software stack.
• Connection troubleshooting: A correctly matched driver can help resolve driver-related detection errors, pairing failures, and unexpected disconnections.
• Support for older Windows systems: Driver packages are available for Windows 10, 8.1, 7, Vista, and XP; check each package’s supported operating systems and architecture before downloading.

How to Install Broadcom BCM20702 Bluetooth USB Device Driver

1. Confirm your adapter and Windows version. Open Device Manager and locate the adapter under Bluetooth, Other devices, or Universal Serial Bus controllers. Check its hardware IDs under Properties > Details, and confirm whether Windows is 32-bit or 64-bit.
2. Choose a compatible package. When selecting a Broadcom BCM20702 Bluetooth USB Device driver download for Windows, match the package to your hardware ID and operating system. Choose the latest version explicitly compatible with your adapter, preferably supplied by the PC or adapter manufacturer.
3. Download and prepare the files. If choosing a free download, use a trusted source and avoid unrelated download managers. Extract the archive if necessary, and review any included installation instructions.
4. Install the driver. Run the supplied installer, or right-click the adapter in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts and restart if requested.
5. Test Bluetooth connectivity. Enable Bluetooth and pair an accessory. For Windows 10/11 troubleshooting, check compatibility carefully: Windows 10 is among the listed supported systems, but Windows 11 support is not confirmed here.

Keep the driver updated when a compatible release addresses a problem you experience or improves support for your system. Before an update, create a restore point where available, and retain the working installer so you can recover if the new version causes issues.

Common Issues and Fixes

• Install fails or rolls back: Run the Broadcom package as administrator and use the version matched to your OEM/Windows build. Remove old Broadcom/Widcomm software, reboot, then retry. Use only signed OEM packages; don’t force unsigned drivers.
• Device not detected: Check Device Manager for “Unknown USB Device” or hidden Bluetooth entries. Try another USB port, disable USB selective suspend, uninstall the BCM20702 entry, scan for hardware changes, then re-pair after reboot.
• Version/stack conflicts: Windows’ generic Bluetooth driver can override Broadcom’s. In Device Manager, manually update to the OEM BCM20702 driver, delete duplicate driver packages, and avoid mixing Widcomm and Windows Bluetooth stacks.
