Windows is automatically installing drivers for my fax modem in Windows 8 / 8.1 / 10. Do I need to do anything?

By default, the drivers for the USB modem are included in Windows 8, 8.1 and 10. When you plug the adapter into your Windows computer system, wait a few minutes while the driver is installed. When the driver is installed, the USB modem appears under Modems in Device Manager. 

To open Device Manager, press the Windows key + X and select Device Manager.

If the driver installation is not successfully installed, you can manually install the driver by completing the instructions in the following FAQ: http://www.startech.com/faq/lsi_install_windows_v78.
