Why rebooting? Doesn't Jaws continue working?

Just trying to open a device is not very costly, so I think it can be
reduced to a responsive enough value (the update interval for instance),
in that case. But the whole device probing loop is costly, so we can't
just reduce the 5000 delay in config.c.

Dave, maybe we can just modify the serialOpenDevice to silently loop
as long as it gets an ERROR_ACCESS_DENIED error, and fail after, say,
having tried for 1 second.

It probes focus each refresh update interval (40ms by default).
