Missing Bus controller driver

On this is as you can see on device manager there isn't a bus controller driver so it won't work unitl you get one.

 

 So I used a program called Aida 64 to find out what the bus driver was called then found the driver on the internet and installed it. You can install it two ways you can run the set up to the driver or click on the update drive button in device manager and direct it towards the installed driver.

As you can see this is the bus controller in device manager.
