I have a USB hub where I can switch between two computers. On pressing a button, the hub disconnects all devices from one computer and then, after a short time, reconnects them to the other computer. Video switching is not necessary!
I am searching a device that simulates a keyboard and mouse to both computers, i.e. both computers see a plugged-in keyboard and mouse all the time. Events from the real keyboard/mouse are then relayed to the currently selected computer.
I know that keyboards have state and more sophisticated gaming mice might also have that. But I am not convinced this problem cannot be solved somehow, hence my question:
Does such a thing exist? If yes, which models are of interest?
