When launching Bricx CC will ask for specifics on tower
port (OK), brick (OK) and finally firmware. If selected
leJOS, the brick type allowed will be forced to RCX,
eliminating the possibility for rcx2.0 to be selected, so
brick will not be found. Selecting standard firmware and
rcx2.0 will let the tower search, but (as expected) errors
will occur with the firmware missmatch.
