Looks like something is wrong with the mouse itself.

The log showed that the mouse disconnected itself during the suspend.  
But then after the resume it reconnected -- presumably this log shows a
cycle where the mouse _was_ working afterward.

Can you provide a similar log for a cycle where the mouse _didn't_ 
respond afterward?  It might not help much, however; most likely it 
will show that the mouse disconnects itself during the suspend and then 
doesn't reconnect.

Have you tried plugging the mouse into a different USB port?  It might 
help.
