If you are not using Big Sur, you shouldn't be using that driver, you should use this one instead. If you are using Big Sur, then please follow these instructions for proper installation - if you don't, it may seem like the installer has completed successfully, but the device would not function as expected. Please follow the steps from the end of the guide to uninstall, then restart your computer and install again per the guide.
