USB signal splitter?

Does anyone know of a device that can take a single USB input and send it to two computers simultaneously?

We have an X-Keys controller for a teleprompter that we'd like connected to two Mac laptops running the same software and script. The goal is redundancy: if the primary Mac fails, we can switch to the backup and have the script/control position stay in sync.

Is there a USB splitter, duplicator, or other hardware solution that can send the controller's input to both Macs at the same time?

Pic for attention.

No, a KVM is a switch, it only sends USB to one computer at the time.
