Query: Simply stopped working

This kvm switch worked perfectly for a little while - a few days. Then it completely stopped working. I put it away and then tried it again a few months later on two different computers. The same deal. It worked for a few days and then quit working. This is very frustrating to the point that the kvm switch is now in the trash. I defintely do not recommend anyone purchase this kvm switch.
