“Connected SpaceMice: 0”
There’s my problem. The SpaceMouse is definitely connected and it works fine in other programs. Like I said earlier, the “Manufacturer” in the driver properties is “3Dconnexion”, so I’m not sure how this could be getting missed.
Edit: I’ve changed the HID enumeration method parameter in SpaceMouse.cpp so that it looks for the VID that Windows says my device is using. The only way I know how to compile this guy is to put it in the engine source folder structure and compile the whole thing, so I’m doing that, (it’s taking forever) and I’ll let you know how I fare with that. I suspect that this is the issue. It is at least an issue, if not the only one.
