Windows 8.1 USB Serial Port Driver – A USB driver is a small piece of software that allows your computer to communicate with your USB devices. Without a driver, your computer would not be able to use your USB devices.
Most USB drivers are already included in your operating system. However, if you are using a older or custom made USB device, you may need to install a driver. Drivers are usually available from the manufacturer’s website.
If you are having trouble with a USB device, the first thing you should do is check for updated drivers. Often, simply updating your drivers will fix any issues you are having.
