Bcm2045a0 Driver Windows 11 Access

The BCM2045A0 is a legacy Broadcom Bluetooth controller often found in older laptops (like Dell Latitudes) or external dongles. Because Broadcom no longer provides direct driver downloads for these older chips, finding a compatible driver for Windows 11 requires using Windows Update or manually installing older Windows 10/8 drivers.  Recommended Solutions for Windows 11 

To resolve a "BCM2045A0" error in Device Manager, try these steps in order: 

Windows Optional Updates (Most Effective)Windows 11 often carries these legacy drivers in its "Optional" catalog rather than installing them automatically.

Go to Settings > Windows Update > Advanced options > Optional updates.

Look under Driver updates for anything mentioning "Broadcom" or "Bluetooth" and install it.

Force the "Generic Bluetooth Adapter" DriverIf no specific Broadcom driver works, you can often force Windows to use its built-in generic driver, which works for basic functionality.

Right-click the BCM2045A0 in Device Manager and select Update driver.

Select Browse my computer for drivers > Let me pick from a list of available drivers.

Uncheck "Show compatible hardware" if necessary, select GenericAdapter (or Microsoft) as the manufacturer, and choose Generic Bluetooth Adapter.

Manual Installation of Legacy DriversDrivers designed for Windows 10 or 8.1 are typically compatible with Windows 11 for this hardware.

Dell Users: The Broadcom BCM2045 v.6.1.0.4700 driver is a common reliable source.

HP Users: Try the Windows 10 Broadcom Bluetooth Driver (sp75330.exe).

ASUS/Others: Third-party repositories like DriverIdentifier host specific versions for various hardware IDs.  Common Hardware IDs for BCM2045A0 

If you are searching for a specific driver version, check your device's Hardware ID in Device Manager > Details tab:  USB\VID_0A5C&PID_2045 (Standard Broadcom) USB\VID_0BB4&PID_0306 (Common in HTC/Vive link boxes) USB\VID_0A5C&PID_21FF (Common in Apple/Bootcamp setups)  BCM2045A0 Drive is unavailable - VIVE Forum

Troubleshooting: When the BCM2045A0 Driver Won’t Install on Windows 11

For Dell Laptops:

1. Visit Dell Support Drivers.
2. Enter your Service Tag or search by model (e.g., Latitude E7450, Inspiron 7559, XPS 13 9350).
3. Go to Drivers & Downloads → Category: Network, Bluetooth.
4. Download Dell Wireless 1707/1820 Bluetooth Driver (version 12.0.1.940 or newer).
5. Run the installer. If it says "Incompatible OS," run it in Windows 8/10 compatibility mode.

Q3: Why does my BCM2045A0 driver work after sleep but not after a cold boot?

Go to Device Manager → Bluetooth adapter → Properties → Power Management → Uncheck "Allow the computer to turn off this device." Also disable Fast Startup in Control Panel → Power Options.

What If Nothing Works? (Hardware Reality Check)

If you’ve tried all three methods and the BCM2045A0 still shows errors, consider these possibilities:

• The Bluetooth module is physically failing – Especially common in older laptops (2014–2016). Replace the Wi-Fi/BT combo card (often a half-mini PCIe or M.2 2230 card like Intel 7265 or 8265).
• Windows 11 removed support entirely – Broadcom stopped supporting BCM2045A0 after 2019. Some users revert to Windows 10 or dual-boot Linux (where the btusb kernel module works perfectly).
• Your system uses a Realtek or Intel Bluetooth chip that falsely identifies as BCM2045A0 – A rare hardware ID mismatch. In this case, use the tool SDI (Snappy Driver Installer) to auto-detect the correct chip.

Option 2: The Quick Forum/Support Thread (Best for Reddit or Forums)

Subject: [Solved] BCM2045A0 Driver Missing on Windows 11 - Here is the fix bcm2045a0 driver windows 11

Body: I recently ran into an issue where my Bluetooth disappeared after moving to Windows 11. Device Manager was showing a generic "BCM2045A0" device under "Other Devices" with a yellow exclamation mark. Windows Update refused to find a driver for it.

If you are stuck in the same boat, here is what worked for me:

1. Don't rely on automatic search. It won't find it.
2. Go to your PC manufacturer's website (HP, Dell, etc.) and search for Bluetooth drivers for your specific model. Even if the latest one says "Windows 10," download it.
3. Open Device Manager.
4. Right-click the BCM2045A0 device > Update Driver > Browse my computer > Let me pick.
5. If the driver is an .exe that won't run, you may need to extract it using 7-Zip and point Device Manager to the extracted folder containing the .inf file.

Hope this saves someone a few hours of searching!

✅ Final check

Once installed, your Bluetooth should work with headphones, mice, etc. Device Manager will show:
Broadcom Bluetooth 4.0 USB Device (or similar) – driver provider: Broadcom, date: 2016 or later.

Hope this saves someone else the headache!
