hi I want to plug the a usb keyboard and a usb mouse into something like a usb hub and be able to press a switch on the hub to turn one or both of the mouse and keyboard off, so the student has to use the other means of input we have ie touchscreen or usb switch (the students have learning difficulties). The couple of switching usb hubs at maplin i saw seem to switch between two usb devices or possibly between two pcs accessing one device , i'm not sure. have you seen anything suitable for my situation? a mouser 4 does allow turning off of mouse buttons, but not turning off keyboard function.
