Kensignton Expert Mouse stopped working with Monterey upgrade
My Kensington Expert Mouse stopped working with Catalina and into my upgrade to Monterey. The fix was pretty easy after to some brief research and with the temporary help of a blue tooth magic mouse. To fix it go to Apple>System Preferences>Accessibility>Pointer Control>Alternate Control Methods, then Enable Mouse Keys. This helped to activate my Expert Mouse again! Hope this helps those that have the same issue.
