Looks like a damn impressive setup for testing keyboards, but could you include if a wireless keyboard requires its wireless dongle to work, or if it could also use either Bluetooth or a Cabled setup? would be useful to know if its one thats shaped to work in a backpack, but somehow requires a dongle to work wirelessly (I know this isnt common, which is why its important to point it out for those odd edge cases, where presumptions may be incorrect)
