Hi Gary,

Please try to uninstall the SpaceNavigator - does your Mac then boot-up with the device plugged in? Do you see suspicious entries in /var/log/system.log?

If you connect the device after booting - do you see the SpaceNavigator under "About This Mac -> More Info -> USB"?

Hello Robert:

Yes, if plugged in after start up, the space navigator shows up in "About This Mac -> More Info -> USB". Still no light on the SpaceNavigator though.

I can not find a file system.log on my computer.

I believe this is a software driver problem/conflict as I can get the SpaceNavigator to work on my laptop. This is a clean install of 3Dconnexion control 1.5.2. I am using mac osx 10.5.4.

I think it is a conflict from migrating/transferring all my data from my old computer to this new computer using Apples migration assistant...

Does the SpaceNavigator light up after you opened the 3DConnexion Control Panel (System Preferences -> 3Dconnexion -> Configure -> Enable LEDs)?

[Gary]

No, the LED will not come on as I toggle enable LED's on and off. The LED's do come on with my laptop.

I would guess either your USB port or the SpaceNavigator are running at the edge of specifications. Please contact technical support. It may be that your device needs to be replaced.
