I don’t know about game controllers, but this isn’t one.
EDIT: Perhaps I should expand on this, @splace73, @WillAdams. Using a small utility program of it’s own, this device maps specific keys on the keyboard, so the keys used to jog the machine on the computer’s keyboard can be mapped to this device when the jog screen is ‘modal’. As it has nine keys, I use the remaining three to adjust the jogging speed.
