Does anyone know of a device with a USB splitter that allows toggling between computers. Wow, that was confusing so here goes again. I want to use a single USB bluetooth keyboard/mouse set for both my desktop and my laptop. I realize there are software programs that allow this, but I don't want to network the computers together. I want to be able to plug the blue tooth receiver into the USB port that splits to two additional USB cables, one for each machine. Then I want the ability to eaily select which machine the signal is routed to and switch back and forth quickly. Anyone know of anything?
