Something that might help as a last resort type thing is to go into regedit and clean out all the mouse related devices listed under HKLM/System/CurrentControlset/Enum/USB you'll need to go through and expand most of the subkeys to find which are mouse related and which aren't. You will also need to change permissions on the individual keys before removing them.
This should cause the system to do a fresh redetect of the mouse and not use any cached driver information for that device type.
