 This is correct behavior. First, mouse may never return to USB port. What for
 do we need moused daemon running? Second, another mouse can be inserted, with
 another protocol.
 
 The correct fix for your problem is correct /etc/devd.conf, containing this
 attach rule:
 
 attach 100 {
         device-name "ums[0-9]+";
         action "/etc/rc.d/moused start $device-name";
 };
 
 If you don't mind, I close the PR.
