I've been using a USB xBox controller on a Dell G3-15 laptop to control NDI cameras. I use the xBox template provided, and most of the time it works fine. But some days I boot up, start vmix with a known good configuration and the controller is basically dead. I have to reboot the laptop.
I've tried unplugging and replugging the controller. It lights up and Windows recognizes it, but VMIX does not seem to.

Is there a way to reset this input on the fly, or to confirm whether the problem is with VMIX, Windows, or something else?

I have tried different controllers and different USB ports on the laptop.

Thanks.
