DOUBLE MOUSE

Step 6 CONNECT USB ADAPTERS

Connect the adapters to the serial cables. The connection for the keyboard will just remain empty for the purposes of this tutorial (yes, I'm leaving room for the DOUBLE KEYBOARD sequel instructable). Plug in one of the USB connections into a PC. When you have one cursor moving properly then plug the other USB connection into another PC. If everything goes as planned then you should now have the power of two PC's in the palm of your hand.... use this power wisely.

You can match the mouse speeds between your two PCs by opening the Mouse Properties:
Start Menu -> Settings -> Control Panel -> Mouse, and then hit the Motion tab.
