Bt-163 Bluetooth Driver May 2026

In Linux, the driver is monolithic within the kernel. The module btusb.ko handles the USB interface.

The BT-163 is surprisingly well supported on Linux, but it requires manual firmware loading.

When the BT-163 is inserted into a USB port, the host controller queries the device for its USB Descriptors. Critical values define how the driver binds to the device: bt-163 bluetooth driver

These values instruct the OS kernel to load the Bluetooth bus driver rather than a generic HID or storage driver.

The BT-163 is typically a Classic Bluetooth 4.0 (or 5.0) low-energy dongle. Most versions use a chipset from Realtek (usually the RTL8761B or RTL8671), though some older clones use Cambridge Silicon Radio (CSR) chips. In Linux, the driver is monolithic within the kernel

The key takeaway: Windows Update rarely finds the correct driver automatically. You need to install it manually.

The BT-163 is a Class 2 Bluetooth USB dongle, typically based on the Realtek RTL8761B or CSR (Cambridge Silicon Radio) 8510 chipset, depending on the manufacturing batch. It is designed to support Bluetooth 4.0 (and sometimes 5.0, though rare) with Low Energy (BLE) support. The BT-163 is surprisingly well supported on Linux,

Typical Specifications:

The problem? Microsoft does not include native drivers for the BT-163 in Windows Update catalogs because it is considered a "generic" or "OEM" device.
