I am using OBS 28.0 and the obs-ptz-v0.15.4 plugin. The camera used is the PTZ-Mini, with a VISCA (Serial) connection, currently on USB COM3.
When starting OBS, the PTZ-Control does not work; the camera does not move. So, I need to close OBS, disable COM3 in the device manager, enable COM3 again, and then open OBS again. The camera control then works normally.
The problem is that I always have to do this every time I start OBS.
I had to create a script to do this automatically.
I upgraded to OBS 30.2.0 and PTZ Controls 0.18.0, but in this version, the control simply does not work, even after disabling and enabling COM3. In this version, the control stopped working, so I had to revert to OBS 28.0 and PTZ-Control 15.4.
