freebsd stable - Nov 2006 - Problem with mouse detection on FreeBSD 6.2 RC1

Hi people,

had anyone problems with mouse detection on FreeBSD 6.1 RC1?

I've bough a new optical mouse and try to use it on FreeBSD, but didn't
work.

By the `moused -i all -p /dev/psm0 -t auto` I get these information
about my new optical mouse:
/dev/psm0 ps/2 sysmouse IntelliMouse Explorer

With the old optical mouse plugged I get these information:
/dev/psm0 ps/2 sysmouse IntelliMouse

Note that the 'Explorer' is not present in the old mouse and works
perfectly.

Has anyone idea about that?

Regards.
