We have the problem, that on all Mac II SI under System 6.0.7 the mouse-cursor suddenly stops to respond to our real mouse-movement. Apple (inofficially) says that it is a known bug. So after a ADB-Bus reset the mouse works again normaly. To do so we used a keyboard macro to reset the ADB-Bus with ADB-Probe. 

Some people tell me to reset the ADB-Bus by reinserting the mouse cabel into the keyboard causing a ADB-Bus-Reset (I think that is not (!) recommended due to a very sensible ADB-Bus DMA-Chip which is about $300 to repair). 

Has anyone a clean solution by patching the wrong routine in system 6.0.7 or in ROM of the Mac II si?
Is this problem solved is System 7.0?
