I use USB input device with "mixed" mice, and X is configured to
see it as the second mouse (what in general isn't necessary, however
reflects most common configuration where a laptop has buitin
mouse/trackpad/...). AllowMouseOpenFail option is redundant -- it only
helps if for some reason X is started without USB drivers.
