Intellipoint software on OS X Mavericks not recognizing Intellimouse I just upgraded my Snow Leopard 10.6.8 system to Mavericks, complete with the latest software updates, and I can't get Intellipoint working with my mouse (MS Intellimouse Optical USB).  Prior to the OS upgrade, I was running an older version of the Intellipoint software (sorry, not sure which version); it required running System Preferences in 32-bit mode to change settings.  After updating to Mavericks, I found that the Intellipoint features no longer worked, and checking System Preferences, I could not open the Intellipoint Prefs pane.  

So I downloaded and installed the latest (8.2.0 v.305) Intellipoint software for OS X.  The preference pane works, but it doesn't see my mouse.  The Buttons tab shows a picture of a USB device being plugged into a USB port, and the Device Info button says "No Microsoft mouse devices found".

Based on a similar question I found for Mountain Lion, I have confirmed that 'MicrosoftMouseHelper' is in my startup items and is currently running.  The mouse functions, but using the standard OS X mouse settings; I prefer the way the mouse behaves when using the Intellipoint drivers and my settings within that.  Any ideas for getting the Intellipoint software to recognize the mouse?
I resolved this by uninstalling the Intellipoint Software (using the provided uninstaller) , rebooting (as requested by the uninstaller), reinstalling, and rebooting (as requested by the installer).  I suspect something went wrong in my prior in-place upgrade of the Intellipoint Software.  I did lose my Intellipoint settings, but I had made note of them prior to uninstalling.
