Realtek Wireless Bluetooth Adapter
USB\VID_0BDA&PID_B85C
What this hardware ID is
USB\VID_0BDA&PID_B85C is the identifier Windows uses for one exact piece of hardware. It is the reason a driver either fits your device or does not - Windows matches this code, not the name of your laptop. Here VEN_0BDA is the company that made the chip (Realtek Semiconductor Corp.), and DEV_B85C is the chip model (Realtek Wireless Bluetooth Adapter).
Every driver listed below declares support for this exact code, so any of them will install on your device. Choosing between them:
- Take one that lists your Windows version and architecture - the badges are in the last column.
- A newer release date is usually the better start. If the newest one misbehaves, an older release is a perfectly normal fallback.
- SHA-256 verified means we downloaded that file ourselves and published its checksum and contents.
