@Campbell Barton (campbellbarton) Okay I got your build https://builder.blender.org/download/patch/blender-3.4.0-alpha+master-D16242.ae908021ac28-windows.amd64-release.zip running, and it resolves the issue.

Missing dependencies?

@BC (exovox) do regular daily builds work for you?

If not would you be able to attempt to resolve the issue? Otherwise it's impractical to investigate the problem on our side.

Okay @Campbell Barton (campbellbarton) https://builder.blender.org/download/patch/blender-3.4.0-alpha+master-D16242.ae908021ac28-windows.amd64-release.zip still won't open for me. Same error. However, another daily build - https://builder.blender.org/download/patch/blender-3.4.0-alpha+master.dc09cc13ea49-windows.amd64-release.zip does open. Unsurprisingly, Blender works fine if I don't import the old settings from 3.3.0. The spacemouse and its side-buttons work. If I do import the old settings, the spacemouse works, but the side-buttons don't.

Hm daily builds for 3.4.0 aren't working - latest throws the same error. But I did run a build for 3.3.0 Beta prior in this thread, and it worked.

I can confirm that after restoring my old preferences userpref.blend and startup.blend to my installed Blender 3.3 version, and turning off the Cadmouse before I start up blender, I get the ndof: using SpaceMouse Wireless message

So, it seems like the unknown device is actually my mouse - the Cadmouse Wireless. I can confirm that when both the Cadmouse and Spacemouse are plugged in when blender starts, then the side button functionality on the Spacemouse doesn't work. Navigation does though.

I can't find the 0xC658 device ID anywhere and Blender doesn't implement it specifically. So it is weird that it works sometimes.

Or, rather... why should this carry over with the user preferences in the first place?

So @Pratik Borhade (PratikPB2123) I downloaded 3.3.0 Beta and started it up. So long as I don't import the settings from the previous blender version, the console does not throw up ndof: unknown 3Dconnexion product c658 and the left side button bring up the ndof settings while the right side button focuses on the active object. However, if I choose to carry over the old user preferences, then the error shows and I cannot open the menu using the side buttons.

Hi @Hans Goudey (HooglyBoogly) any chance you've managed to try this out? In Blender 3.0 the device simply just doesn't work.

I also hope we can keep this option, as I have tried alternatives, to no avail. I have a lightweight setup with laptop, stylus and eGPU. I only just got a mouse, and I would still prefer to keep the option of travelling without it.

Thanks!

P.S. forgot to include that the desired behaviour is that... the side buttons work! haha
