The most common cause is the absence of the Broadcom driver package; other causes include corrupted WIDCOMM stack installations or a mismatch in USB VID/PID values. Now that you know the causes, let’s discuss the solutions.
1. Run the Bluetooth troubleshooter
If you’re having this issue on Windows 10, your first step should be to see if Windows can fix it automatically using the built-in Bluetooth troubleshooter. Sometimes, this utility can resolve problems with your Bluetooth drivers or settings. Several users have reported that running the Bluetooth troubleshooter and applying its recommended fix has solved their issue.
2. Install the Broadcom Bluetooth driver (Windows 10 Only)
If you have the BCM20702A0 driver error on an HP laptop or ultrabook, it’s probably because the necessary Bluetooth driver is either missing or needs to be updated. HP laptops in particular are known for having compatibility issues with certain Bluetooth drivers. This issue is also common if your computer doesn’t have built-in Bluetooth and instead uses a Bluetooth adapter, such as the Insignia 4.0 or a similar device. If this sounds like your situation, you can likely solve the problem by installing the Broadcom Bluetooth driver package.
3. Uninstall Every Bluetooth and USB Controller
If the troubleshooter didn’t work and you’ve confirmed it’s not a permission issue, you might be dealing with a corrupted Bluetooth driver or a problem with your USB controller (especially if you’re using a Bluetooth dongle).
4. Perform a Repair install/Clean install
If none of the solutions above have worked, it’s likely there’s a deeper problem with your operating system that’s affecting Bluetooth. If this is the case, you may need to refresh your Windows installation. To do this, you can either perform a repair install (in-place repair) or a clean install. A repair install takes a bit more time and requires you to use a Windows installation disk or USB. The benefit is that your personal files, installed programs, games, and most settings will be kept. A clean install doesn’t require installation media, but you’ll lose all your personal files and programs unless you back up your important data first.
