I have a number of devices I switch between computers. To do this, I plug them
into a USB-3 hub and plug the hub into a switch to select the computer I am
talking to. This configuration worked fine under Leap 42.1, but I just upgraded
to 42.3. My keyboard, SD card reader and track pad all switch between this
openSUSE and OS/X Sierra just fine. However, openSUSE 42.3 cannot see the
mouse.

Consequently, I have to plug the mouse into the back of the computer.
Fortunately, I have another mouse so I am okay, but still....
