USB controller: installing drivers and troubleshooting

The USB controller controls the USB connections of your computer. So that it can communicate with other components, it is necessary that you install the correct drivers. This will already fix most of the problems.

How do I find and install the drivers for the USB controller?

Peripheral devices such as mice, keyboards etc. are usually connected to the computer via a USB connection. This in turn is controlled by the USB controller, which requires the latest driver software to function as desired.

1. First try to update the drivers for the USB controller via Windows.
2. Press the Windows key and type in "Device Manager". Click on the corresponding search result.
3. Here you can see some host controllers for your USB connections. If a USB controller does not work correctly, it is provided with a warning symbol here.
4. Now right-click the corresponding USB controller and select "Update driver" in the context menu.
5. Then follow the instructions.
6. Alternatively, you can install the drivers manually. To do this, search for the relevant software on the website of the manufacturer of your mainboard or on our driver download list and download it.
7. Then double click on the downloaded file to install the drivers.

Troubleshoot the USB controller

If one of your USB devices is not working properly, installing the drivers for the USB controller often helps, but not always. Some possible other causes that you can consider include the following:

• Are the latest drivers installed for the peripheral device itself?
• The USB connection may be defective. Connect the device to another free USB slot on your computer.
• If it does not work, test the device on another computer. The device or the cable may be defective.
• Restart your PC and then check again whether the USB controller recognizes the device.
