Space Mouse not working in latest WIP

[Cesare2 (Cesare)]

Hi, I updated WIP last night to version (9.0.26146.14285, 2026-05-26), and my SpaceMouse Enterprise stopped working. Symptom: all the slots on the device screen show Application Use, and the knob does not work.

I am using this on Windows 11, and the device works perfectly in Rhino 8, so I would rule out a hardware or driver issue. It was also working fine in the previous WIP version.

Note: The SpaceMouse works on Mac, although all the controls are reversed, so it is pretty much unusable there as well. On Mac, everything also works as expected in Rhino 8.

Try running the SpaceMouse command.

Control reversal may be due to the selected “Mode” in SpaceMouse > Popup_Menu

[Cesare2 (Cesare)]

Strange, the SpaceMouse command autocompletes, but then Rhino says “Unknown command”.

This may or may not help:

Is the 3DConnexion 3D Mouse plug-in enabled and loaded?
PlugInManager or Options > Plug-ins

If the plug-in is not enabled, check it to enable it, then restart Rhino.

Just right-clicking and choosing to load should be enough after enabling it, there should be no need to restart.

Disabling a plug-in requires restart if it is already loaded.

Thanks a lot, I even saw that post when it appeared, but I did not have the issue at the time so I wrongly assumed it was something different.

Turns out it was not, changing Rhino.Options.SpaceBall.UseLegacy to true fixed the issue.
