USB Bluetooth Driver (ALPS) Driver

The USB Bluetooth Driver (ALPS) driver enables Windows to recognize and communicate with compatible ALPS USB Bluetooth hardware using Cambridge Silicon Radio technology. It is intended for users setting up a Bluetooth adapter, restoring connectivity after reinstalling Windows, or troubleshooting an unrecognized Bluetooth device.

Choose a package that explicitly supports your Windows version and hardware ID. Listed operating systems include Windows 10, 8.1, 7, Vista, and XP, but individual driver packages may support only some of these versions. If you are comparing Windows 10/11 compatibility, do not assume that a Windows 10 package also supports Windows 11.

Key Features

• Bluetooth hardware recognition: Helps Windows identify a compatible USB Bluetooth adapter so it can be configured and used.
• Wireless device connectivity: Supports communication with compatible Bluetooth peripherals, such as mice, keyboards, and headsets, depending on the adapter and installed Bluetooth software.
• Driver restoration: Can help restore missing Bluetooth functionality when the cause is an absent, damaged, or incompatible driver.
• Support for older Windows systems: Provides a driver option for listed Windows versions when the selected package matches the operating system and adapter.

How to Install USB Bluetooth Driver (ALPS) Driver

1. Identify your adapter. Open Device Manager and locate the Bluetooth adapter or unknown USB device. Under Properties > Details > Hardware Ids, note its identifiers to check against the package information.
2. Check system compatibility. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. Before choosing a USB Bluetooth Driver (ALPS) driver download for Windows, verify that the package supports both your hardware and system.
3. Download the matching package. Select the latest version that explicitly supports your configuration. If a free download is offered, verify its source and scan the downloaded file before opening it.
4. Install the driver. Extract the files if necessary, then run the included installer. If no installer is provided, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and test. Restart Windows if prompted, check Device Manager for warnings, and try pairing a compatible Bluetooth device.

Keep the driver updated when a compatible update addresses connection problems, stability, or security. A newer release is not automatically better for older hardware, so prioritize a verified match over the highest version number. If an update causes problems, use Device Manager’s Roll Back Driver option when available.

Common Issues and Fixes

• Install fails or rolls back: Uninstall any existing Bluetooth software and remove hidden Bluetooth devices in Device Manager. Run the ALPS/CSR installer as administrator, temporarily disable antivirus, and avoid mixing it with a generic Windows Bluetooth stack.
• Device not detected: Plug the USB Bluetooth adapter directly into a rear USB port, not a hub. In Device Manager, remove any unknown/USB device entries, then rescan. Confirm the adapter’s VID/PID matches the ALPS/CSR package.
• Version conflicts: Delete the current Bluetooth adapter and driver in Device Manager, reboot, and install only the correct ALPS/CSR package. Do not install multiple Bluetooth suites; if Windows replaces the driver, roll back or reinstall the vendor driver.
