It may be that Xastir isn't a member of the owner/group that has
access to the device, or that permissions are not sufficient for the
user Xastir is running under.  The below should fix it, giving
Xastir "SUID root" privileges.  Xastir is smart enough to drop those
privileges when it doesn't need them, and reclaim them during the
short periods when it is messing with the ports:

     su root
     chmod 4755 /usr/local/bin/xastir
