Connecting is very easy. On the one hand, the four devices, both PCs should be available to append via USB. The USB switch has on the other hand, about 1.5m long USB cable for direct connection, the respective PCs. Once connected, the switch does exactly what it should. The switches takes place via a knob which is attached to a separate cable. Switching is easy and makes keinerleit problems.
However, what is missing is the power supply for the switch. The switch must be powered via mini USB cable. I recommend a simple mini USB charger, which gives it at Amazon for 4 euros.
