After investigating this issue carefully, you might discover that there are many reasons why the causes of this can be happening. It is possible that each and every one of these following potential culprits relates back to a specific scenario or behavior:

Outdated driver version :-

Bluetooth functionality can break due to outdated drivers on Windows 10. If you find yourself in this scenario, simply download our USB Bluetooth Adapter and use Device Manager to update to the latest version available.

Incompatible Bluetooth driver:–

In some cases, this problem may also be caused by trying to use a driver that is not fully compatible with your OS version. If this is the case, you should be able to fix it by using Device Manager to install a generic equivalent driver.

Device manager is unable to install the correct driver version :-

Some users have reported that this error message appears on their computer screens because the operating system is attempting to install an incompatible driver. In this case, you can use a 3rd party driver update tool to automatically update your drivers and get rid of annoying issues like device manager conflicts.

Critical Bluetooth Services are Disabled :–

If you have manually disabled some Bluetooth-related services or if you’re using a service optimizer app, you might see this issue occurring because the Bluetooth Support Service and Bluetooth HandsFree Service entries are disabled in the registry. In this case, you can fix the issue by modifying the startup type of these 2 services.

Bluetooth stack error :–

Certain USB devices, when plugged into a computer running Windows 7, do not appear to be detected by the OS and therefore won’t function as expected. These types of issues are usually caused by OS architecture not being able to properly communicate with the device in question. In order to resolve this problem you should install the Bluetooth Stack program.

System file corruption :–

Under certain special circumstances, you might expect to see this error occurring due to some kind of corruption that is affecting the Bluetooth driver or some associated dependencies. In this case, your best chance at fixing this issue is to go for a repair install or clean repair procedure.

Now that you know every potential cause, there is an extensive list of methods that has been successfully used by other users to fix the driver issue related to CSR8510 A10:

To Fix CSR8510 A10 Driver Error Follow These Steps:-

Procedure 1: Updating the Driver via Device Manager

One important thing you can do if this happens is check Device Manager to see if you can update the current version of CSR8510 A10. This might be effective in situations where the issue has just started occurring after Windows Update installed a pending infrastructure update.


Several affected users were able to update the driver via Device Manager. Once the next computer startup was complete, they were able to use their Bluetooth dongle normally. Are you using a Bluetooth dongle that might not be functioning correctly?

If you haven’t already, follow these steps to reprogram the CSR8510 A10 device driver in Device Manager:

  1. Open the Run dialog box by pressing Windows key and R on your keyboard at the same time. In the text box, type “devmgmt.msc” then press Enter on your keyboard to open up Device Manager.

Procedure 2: Installing a generic Bluetooth Driver

According to some affected users, there is a simple workaround to fix this issue. It seems that implementing the use of generic Bluetooth drivers instead of the ones supplied by Microsoft is all it takes to get things up and running again. A lot of affected users agree that this one simple tweak has allowed them to change their “Driver is unavailable” error to just simply “Working Fine”.

We didn’t manage to find an official explanation for this method, but affected users are suspecting that this method is effective because it goes around a native driver conflict related with a Windows Update.

If you haven’t tried replacing the dedicated driver with a generic equivalent before, follow the instructions on how to do it below:

  1. Press the ‘Windows’ + ’R’ keys to open up a dialog box that launches the Run application. Type ‘devmgmt.msc’ inside the text box and press Enter to open Device Manager. When you’re prompted by the UAC (User Access Control), click Yes to grant access.
  2. Once you’re inside Device Manager, scroll down through the list of device types and expand the drop-down menu associated with Bluetooth. Once you’re inside, right-click on your Bluetooth dongle and choose Update driver from the context menu that just appeared.
  3. Utilize the Auslogics Driver Updater in Similarity Mode
  4. On the next screen, click on Browse my computer for suitable driver software from the context menu that just appeared.
  5. Once you get to the next screen, click “Let me pick from a list of available drivers on my computer.”
  6. Next, select the first choice from the list of available drivers. If you have to decide between multiple options, simply choose the first option with a blue Bluetooth logo and hit next before following on-screen prompts to complete the installation of the generic driver, then restart your computer.

If you are still encountering the same CSR8510 A10 Driver error even after making the switch to a generic Bluetooth version, move down to the next potential fix below.

Procedure 3: Utilize the Auslogics Driver Updater in Similarity Mode

If the installation methods from Device manager above haven’t worked for you, you should try installing the latest driver for your device by using Auslogics Driver Updater.

However, if you’re on Windows 10, it’s possible you’ll need to open this program in Compatibility mode with Windows 7 or maybe even both (that is, Windows 7 running on Windows 8) – that is in order to avoid an OS-specific glitch. Some affected users have confirmed as a solution the only thing that allowed them to fix the CSR8510 A10 Driver error was by using a combination of these two operating systems together.

To resolve the ‘The Auslogics driver was reloaded and it may not work correctly‘ error, follow these steps:

  1. To access the download link of Auslogics Driver Updater, open your default browser and visit the link provided to download the latest version.
  2. After you download the latest driver updates for your hardware, don’t launch them immediately if you are running Windows 10 since you might experience problems. Once the download is complete, navigate to your Downloads folder and right-click any of the files that appear there. Then choose Properties from the context menu.
  3. Once you’re inside the Properties screen of your setup application, access the Compatibility tab. Once there, check the box associated with Run this program in compatibility mode and select Windows 7 from the list of available options.
  4. Click Apply to save the changes, then double-click on the application’s icon and let the installation begin. Be sure to follow the on-screen prompts and, once you’re finished updating your drivers, restart your computer for all of the changes to take effect!
  5. Once the driver version is updated, restart your computer and check if the issue has been fixed.

Procedure 4:Enabling the Bluetooth Handsfree service and Bluetooth Support service

As it turns out, you could also encounter this problem if a manual user interaction or an optimizing application has altered the Startup Type of one of your Bluetooth-related services – like Bluetooth Support Service and Bluetooth HandsFree Service – to disable them.

If you or a program disabled the Automatic startup type when you installed the anti-virus program, then access the Services screen to ensure that both the Type and Start options are set to Automatic so they can start automatically at boot.

If you haven’t tried this fix yet and think this solution could be useful to you in the future, we recommend taking these steps:

1.    Press Windows key + R to open a Run dialog box. Once you’re prompted by the text box, type “Services.msc” and press Enter to open up the Services screen. If you’re prompted by the UAC (User Account Control), click Yes to grant admin access.

2.    Once you’re inside the Services screen, scroll halfway through the list of services until you see the Bluetooth Support Service. Double-click on it to open its Properties dialog box.

3.    Right-click on the Bluetooth Support Services icon in the Notification Area and select Properties to get to its properties window. In here go over to the “General” tab and click the dropdown menu next to “Startup type.” Choose Automatic from this list, which should just have these two options.

4.    In the Services menu, click Apply to save your changes. Then click Bluetooth Handsfree Service and follow steps 2 and 3 again. Before you restart your computer, save the configuration changes.

5.    After your computer has successfully booted up, see if you are able to use your Bluetooth dongle.

Procedure 5: Installing the Bluetooth Stack program

If you’re encountering this issue with your CSR drivers while using Windows 7, you might be seeing the CSR8510 A10 Driver error related to a missing Stack architecture.

Several affected users have reported that they have managed to get the error resolved by installing the Toshiba Bluetooth Stack on their computer. This program is confirmed to work with the vast majority of CSR drivers and can be easily downloaded from several reliable sources outside the Toshiba ecosystem.

If this scenario is applicable, follow the on-screen instructions to install the Bluetooth Stack program supplied by Toshiba:

1.     Open your default internet browser and navigate to a downloadable software page for the Bluetooth Stack.

2.     Once you’re inside, click the “Download Button” to download the latest version of the program.

3.     Once the download is complete, double-click on the installer and click “Yes” if you’re prompted by the UAC (User Account Control) prompt.

4.     At the Setup screen, follow the on-screen prompts to complete installation of Bluetooth Stack. When finished, restart your computer.

5.     After you manage to install the Bluetooth Stack Program and the next startup is complete, you should detect the Bluetooth Adapter and it should begin working right away without any problems.

Procedure 6: Refreshing every Windows component

Some USB ports can be faulty and thus corrupt your computer. In this case, you could try to upgrade the port by updating drivers or installing newer hardware, but there may be an underlying issue with your system file. In this case, all of your personal data, music and files stored on the infected device can get deleted with a single format format.

If this scenario is applicable, you should be able to fix the problem by basically refreshing every involved Windows component ensuring that every potentially corrupted Windows file is replaced with a healthy equivalent. The two way forward in doing this are:

Clean Install – this is ideal if you want the simplest procedure out of all of those and you have already backed up your personal data, or you don’t care about losing the files you are currently storing on the hard drive. This should be the first choice for you. You can install a new Operating System without having to insert or plug in an installation disc (via Windows GUI menu).


In case you don’t have time to backup your OS drive or in case you simply don’t wish to carry out such procedures, a repair install should be your first course of action. This method will allow for the main bulk of personal files, applications and games to be preserved along with any user preferences that may otherwise have disappeared from your primary installation disc.
