CSR 4.0 Harmony Bluetooth Drivers

The CSR 4.0 Harmony Bluetooth drivers available on OEMDrivers are designed for USB Bluetooth dongles using CSR chipsets like the CSR8510. These drivers enable full Bluetooth stack functionality, including support for audio devices, file transfers, and peripherals such as keyboards and headsets. They use Bluetooth 4.0 with low energy (BLE) for efficient performance and are compatible with Windows XP through Windows 11. In many cases, installing the Harmony driver unlocks features not supported by default Windows drivers.
