Do I get it right that the shutter release works as expected on the R-Pi and another Linux computer, but not on your laptop?
In that case, it must be a matter of software on the laptop, I'd think. What system do you run on the laptop then?
My first idea would be that the shutter release is not correctly identified on the laptop - either the driver is missing or it is not corretcly set up in Indi. Check in the Indi control panel which USB device is identified as the shutter release and which is identified as the camera.
