How to Make a Serial Mouse Into a USB Mouseby C. Taylor
A serial mouse connects to your computer through a serial port. These types of mice were prevalent many years ago but have since been replaced with PS/2 and USB connectors. Many new computers no longer include serial ports, so if you want to nostalgically use your now-ancient mouse, you'll need to find another way to connect it. One solution is to use your USB port with a serial-to-USB adapter.
Plug your serial mouse's cable into a serial-to-USB adapter.
Turn the thumbscrews clockwise to lock the serial connector to the serial-to-USB adapter. This essentially transforms your serial mouse into a USB mouse.
Plug the USB connector of the serial-to-USB adapter into an available USB port on your computer. Windows 7 automatically recognizes and installs any necessary drivers for your newly transformed USB mouse.
