How to install

  1. Check that this is the right driver. Open Device Manager (right-click the Start button), right-click your device, choose Properties and look at "Hardware Ids" on the Details tab. The value should match one of the supported IDs below (more about hardware IDs).
  2. Extract it to a folder. If the folder contains setup.exe or install.exe, run it as administrator.
  3. If there is no installer, right-click the device in Device Manager, choose Update driver, then "Browse my computer for drivers", select the extracted folder (leave "Include subfolders" ticked) and click Next.
  4. Restart the computer and check that the device no longer shows a yellow warning sign in Device Manager.

Windows 11 is not listed by the manufacturer, but drivers made for 64-bit Windows 10 usually work on Windows 11 as well.
