I'm trying to get my mouse mat to connect but it just doesn't show up. Is it possible to add things that don't normally have a program to control them? It's just a button on the pad.
If it doesn't have an official control app then we most likely cannot add it. Usually button-controlled RGB means that the device just uses the USB cable for power, not data, so there is no control protocol we can send to the device to control it. We use the official applications to reverse engineer the control commands.
