USB trigger for an interactive display.

Hi, does anyone knows any place (preferably UK) to buy USB cables with ready interfaces (programmed or easy to programme) so when wires coming out of USB will be connected to each other (using an external switch provided by client) I can trigger events in Unreal?

Or at least what to look for, as currently everything I try to google takes me to VOTOL which seams to be designed for motor control :person_shrugging: .

USB would need to only trigger a keystroke of a single button so I can start an event in Unreal.

Cheers
